I could go into a long, detailed, breakdown of how bad TeXStudio is but, frankly, if they want UI/UX work they should pay for it. Which they clearly don’t.

It’s... decent enough in the pack of “open source UI” but that isn’t a high bar.

Here’s the thing about that (oft repeated) line about WYSIWYG vs WYSIWYW: it’s bullshit.

There’s no justification for it other than the deficiencies of the tooling and tool chain. It’s an excuse.
