Here in the studio we created an unthinkable workflow: we have an empty premiere project file, which we copy to the folder of each new project. A way to bypass this horrible new interface.
For now, this is how we will proceed.

We always use explorer to import clips,
It's much faster, we don't have to build thumbnails, we can rename just for import,
view date and filesizes, do a quick selection, switch to different directories etc.

I find that the new Import window starts to lag heavily as soon as any clips are selected for import. Kind of defeats the purpose.

I couldn't agree more.

"Seriously, no "Create New Folder" option in the import window? Why have all of that if you can't modify it to your liking? BORING."

Thanks for the feedback. Can you please clarify your ask? Creating new projects uses the same number of mouse clicks or keystrokes as the old flow. You type in a name, optionally choose a folder and hit enter/return or click the Create button. When you choose a folder you can also bring up the operating system dialog box to make a folder.

You create new Bins by selecting that in the Import Settings panel and providing a name.

Seriously, no "Create New Folder" option in the import window? Why have all of that if you can't modify it to your liking? BORING.

Also what's with the new Export window requiring that I set a name for the file AND folder destination separately?! Previously I could click on the export path, click on a previously exported item, update the number iteration in the filename and accept. Now I have to once again exit Premiere into Explorer, navigate to the output folder, copy the name of the previous video version, jump back into premiere and paste the name there. This makes export versioning SUCK.

Here's my idea: STREAMLINE, don't BULK.

Start referring to the update as "Ugly Sonic." Maybe that will clue in Adobe to what they could gain by listening to their customers. The movie producers listened and salvaged a franchise.

I strongly dislike the new import and export windows

100%

At my office we have a very specific way of naming exported files; with this new UI we have to go into our files to find the name of our most recent export and name the new one accordingly instead of just changing 1 little thing like we used to. This wouldn't be an issue if we only had a few projects but we have several.

Its is incredibly inefficient...

Adobe please take us back to the previous exporter... if it ain't broke, don't fix it you know?

Adobe, please listen to the large amount of your user base.
These implementations were a mistake and need revisioning.

A list of just some of the problems with the new export interface:

1) Overwrites existing files (such as past exports) with no warning!!!

2) Can't create a new folder from the save location dialogue box!

3) New save location dialogue box doesn't show existing files, so when saving a new version of an export, you can't just copy-paste the old filename. Now you have to open the file browser, navigate to the save location and copy the filename from there. This is extremely time consuming.

4) When exporting from in to out points (such as exporting a single frame jpg), the export preview doesn't automatically show the first frame of the export. Instead it always shows the first frame of the sequence.

5) When it's necessary to adjust a single export setting (i.e. when creating a whole preset isn't necessary), you have to mouse-click to twirl down the settings rather than just using the scoll wheel like you could in the past.

6) When using a massive UHD display, you have to move over to look up in the top left corner to adjust settings and filename. Then move over again to find the export button in the bottom right. The whole thing is way too big.

7) The export button must be mouse-clicked. Hitting enter/return doesn't work.
