I tested filetype specific icons (from Seti_UI, with a .tmPreference for each type) with build 3066/3067.
I noticed that on startup, if I have folders and files already in the sidebar, the file icons will sometimes be invisible. I then have to click on a sidebar entry to make them visible.
Is there something wrong on my end or with ST3?
Also, and I think this is known, ST3 doesn’t differentiate, for example, between .c and .cpp files, so both types have the same icon, which is a bummer.
