Increase Font Size on UI
The font size after long hours on AE is too small. After spending long days on the program, having bigger font would help.
I work with two 4k displays. A Dell U2718Q and a Phillips 276E8V. Both of them are set to high-resolution ~ (3840x2160). At this resolution, the font used to create the User Interface in After Effects is very small. The low contrast of the font color hurts legibility as well.
After long animation sessions, I find myself with much more eye strain, headaches, and fatigue than when I'm working in other applications.
Adobe Illustrator's UI fonts and icons continue to get larger with every major update.
Adobe Photoshop's UI is customizable.
It's time we were able to have more control over the UI in After Effects. Considering that your user-base is working in 4k, it is an important user experience and accessibility consideration to allow a more flexible and customizable UI.
