'Stage all' and 'Unstage all' works fine so far.
'Discard all' does not work for new files. They don't get removed as expected.
Furthermore I would like it to have the buttons in the 'Changes' resp. 'Staged changes' header lines with the same hover behaviour as for single files. See VSCode.
And for 'Discard' you should use the same Icon as it is used for discarding single changes.

In additional to @jbicker's comment it would be nice to add these action in the drop-down menu.

thanks guys, I'll follow what vscode has as a ui/ux experience for these commands and update the PR accordingly.

I made the necessary updates both adding the inline toolbar to the Staged Changes, Merged Changes and Changes, as well as adding the new menu items in the context menu for the git-widget. I also addressed the issue regarding the discardAll for newly created files. Please let me know if anything else is needed. @jbicker perhaps you can help in making the toolbar for the header items look better.

Menu and 'Discard all' works well now as the buttons in the respective headers. Thanks for that!
But as I said in code comments please use just the buttons in headers that make sense for the respective context.

thank you for your feedback @jbicker, I addressed your comments, please let me know if I missed anything :)

Looks good to me now. Works great. Thanks!
The layout of the the buttons in the headers could be improved as you already mentioned. It is not only CSS, but also a bit DOM that has to be changed. I could take look at it in a different PR.
