Fix the sidebar, then hide app.js, we can still see it as checked in sidebar.

Did you hide the app.js it via the popup menu or how?
Yes, hide it via contextmenu.
I found this bug when I try to make a gif for PR #315
Here is the gif:
I used contextmenu to hide app.js

Thanks, this is indeed a bug.
@bregenspan would you have time to look into this as you were the one who built the initial feature in #246?
@valscion yes, I can take a look at this!
Fix is available in release v3.5.2 :tada:
