This issue was mentioned in Preview/Markdown buttons overlap with Review File action buttons - #4 by krasznai , but was closed.
tl;dr - I Iike the position of Undo/Keep under the tabs, and I like the Markdown/Preview buttons, but please move the Markdown/Preview to the left of Undo/Keep.
I like the Markdown/Preview buttons. It’s much better than the Ctrl+Alt/Option+Shift+V or menu experience of VS Code. However, it causes a major UX fail, IMO, because it directly affects the code review process.
When I’m reviewing files, I expect the position of the the Undo and Keep buttons to be sacrosanct, because accidentally clicking Undo can cause problems that take time to unwind–mainly if you don’t realize you did it before committing. This is why I like the current design of having them in the top bar under the tabs (they seem to move around).
The problem happens when you Undo or Keep the file, and the next one is Markdown. The buttons shift and the next click selects Preview, or whatever. Not a big deal. The larger problem is when you go from Markdown to code, and you click Undo inadvertently. It reminds me of the old trick of having a dialog box move when you go to click the OK or Cancel buttons. The only difference is that the trick dialog is more noticeable.
