I cannot reproduce it.

From you screenshot, I see a horizontal scrollbar there. Please check if that's reason you don't see the inline button.

@Eskibear I made a short video clip. Please check: https://youtu.be/YHU38F7k9zA

yes, I already see it from your screenshot. There is a horizontal scrollbar, and I guess if you scroll it you'll see the inline button.

Please check if you explicitly turned workbench.list.horizontalScrolling on.

WOW, you have very good eyesight. I never realized there is a horizontal scrolling bar down there. 😅 👍

Yes, you are right. I do have a "workbench.list.horizontalScrolling": true user setting been defined explicitly long long time ago.

I think #702 can solve this UX issue if workbench.list.horizontalScrolling been enabled.
