I want to mul languages can be visible at the same time which can help us fit this software for Non-native English people

Just like how it works in Premiere.

And the translation in Chinese is not so accurate.
e.g.
en: channel → zh: 通道 (not 声道)

In the attached photo you can see I've created an adjustment brush mask for the bird I photographed. I can edit the bird this way but would love to also be able to create an inverted mask of the adjustment brush mask. This would be a mask only for the background not the bird/opposite of my first mask. This way the background can be edited and the adjustment brush layer for the background can be created without me having to paint aa new layer erasing the bird so that background is targeted

Writing scripts for after effects is fun as well as frustrating, but scripts allow for the community to bring features to After effects to ease workflow processes.
And I think adding the possibility to access After effects native color picker would open up a great amount of potentials for scripts.

Currently we have to adress OS native color pickers which from my experience doesn't match colors with AE.

In the Render Queue, when I add a token from the drop down menu to a File Name and Location template, it places the token at the start of the string. I think new tokens should place where the cursor is currently sitting. Would be helpful when adding lots of tokens to a long file path.

Rendering is a part of the experience we all just sit around waiting for. We want to be able to take a nap or go get some food without worrying my render has failed or that my computer is just sitting there when I have deadlines.

Introduce a function via Adobe CC perhaps that would allow you to track and notify you about the completion of renders in After Effects, Premiere or Media Encoder.

Here is a concept video designed to give you some ideas: https://youtu.be/G9kQEchDun0

now, that file tab is different fonts and size from others so it is difficult to use the bar.
ファイルタブが他のタブと違ってフォントと大きさが違い、非常に使いづらいです。修正を希望します。

Keyboard Shortcut for Layer > New > New Shape Layer

After Effects is an amazing application, however, I've observed the Keyboard Shortcuts window needs some much needed improvements (this applies to Premier as well). Here are my suggestions:

• Make it a non-modal window

• I really don't understand why this dialog was created as modal in the first place. To more quickly learn and reference the myriad number of keyboard shortcuts, it would be invaluable to be able to left open on second display while you work.

• Add the ability to create and display lists of favorite shortcuts. This way users can more quickly reference their specific shortcuts.

From 2020CC, C4D lite is separately installed. When AE is installed or update, C4D is installed replaced currently installed version. This behavior is very bad for commercial Cinema 4D users. In AE installation process, please check Current version of C4D and if R21 is installed, please don't installed Cinema 4D. It should install C4D lite, when R21 is not installed.

I was surprised to see that AE overwrote my previous render of the same name without any warning or notification. (In Windows 10 Pro > Composition > Add to Adobe Media Encoder Queue > Quicktime > Render) Bad impolite AE - it should never overwrite a Windows file without warning. Please add warning and opportunity to change name.

Adding/Removing items in the Dropdown Menu (DDM) should not reset any keyframes or expressions in other comps when using Master Properties.

Likely, anyone using the DDM w/ MPs is doing some complex rigging, and having to start over from scratch if you need to add an option breaks almost any usefulness from being able to combine these awesome features!

A nice UX would be to ask if you wanted to reset any keyframe or expression data, or let you choose to leave it, and deal with any resulting consequences like expressions breaking, etc.

Add a checkbox to every property editable in every layer, when the checkbox is ticked, it can be treated like "master properties" for precomps, and pressing a single letter shortcut can reveal all bookmarked master properties on every layer, making the layer easy to manipulate.

Overall, the swatches should be the same. Now Illustrator and InDesign have the one that are really good (folders...). Photoshop, After Effect, Premiere... don't have the same. As people switch often from one to another and another app, it would be better to make these tools the same. The use of .ase should also be included in all possible apps and creative cloud.

Since the last update for After Effects, Previewing the audio by pressing period now plays silence for the firt half second of preview, making it impossible to use this method for syncing audio events

One of the bigger frustrations I have with AE comes up when I open a project created by someone else, and the AE UI converts to THAT person's layout. I can think of 0 instances in which that would be of any use.

I know I can go to Window->Workspace and call my saved layout back up, but why should I have to? Please change this behavior.

What would be great is if you could create folders inside layer panel...so you can group together layers...and obviously name the folders etc. making it easier to work with folders rather than stacks of coloured layers.

options to view layer controls are sometimes off sometimes on. You have to switch them on manually per composition which is mildly annoying. It would be great if there was an option in the preferences to select that all compositions should have the layer control options ON.
