See images below of the various different icons across the UI at x2 with some comments. This is by no means exhaustive but contains the major icons:

General comments

• Since color is used so sparingly throughout the UI, it draws additional attention to the icons that feature red and green in particular. Clear output should have not have a particularly strong visual presence imo.

Explorer

• Why is the folder filled in brown and not white?
• Why does the collapse all button feature a blue -, why is it a different blue than the one used in the status bar?

Search

• Why is the red x an inconsistent style with the x used elsewhere?
• Why does the clear icon feature a different light gray than the other icons?

• Why is there a dark border around these icons in particular?

Git

• Why is the tick icon a different weight, why isn't it solid?

Debug

• Why is the debug output icon so short?

• Why is the deactivate breakpoints button feature a circle filled with black (vs transparent used elsewhere)

• Why is the close all button filled so it's inconsistent with the collapse all?
• Why does the close all button button have a black border when collapse all doesn't?
