# Current Situation

Currently, the Vitest extension action buttons are rendered outside the viewport when test names or nested folder structure are longer than the panel width:


This renders these buttons unreachable (without taking significant effort to reach them).

# Desired Situation

The Vitest extension action buttons should stick to the **right side** of the panel viewport (trimming the script text):


See the corresponding [issue about the **NPM Scripts** panel in VS Code](https://github.com/microsoft/vscode/issues/251722) where this issue has been fixed earlier this year.

I already opened an [issue in the **vitest-dev/vscode** repository](https://github.com/vitest-dev/vscode/issues/810), but they think it's the VS Code respository that should fix this issue.
