Checkpoints UI Polish #256071
Description
Quick list of UI polish issues from first round of Insiders release feedback/testing.
1. Button shouldn't lose opacity on hover.
Expected: The button should get lighter when moving from hovering on the container to hovering on the button itself.
Actual: Button loses opacity and you can see the dotted line through it.
2. Buttons should use sentence case.
Expected: Buttons should follow the VS Code convention of using sentence case instead of title case, and feature names should not be capitalized unless they're proper 1P features. Specifically, "Restore checkpoint" and "Redo last request".
Actual: Both buttons are capitalizing every word.
3. Edit button appears empty sometimes.
Expected: Edit button appears when hovering over the input message.
Actual: Occasionally the container appears but is missing the icon.
4. Too much space between the last response and checkpoint line.
Expected: Spacing between input message, checkpoint line, and output/response message is equally distributed.
Actual: There's a large gap after the output/response message, even considering room for the toolbar.
