Please focus "Tags" input after click on "Tag last untagged time"
Maybe a Bug or missing Feature.
Using "Tag last untagged time" as described on
on Windows 10.
The Cursor blinks on the "Tags" input field, but typing do NOT appear there.
Have to click it with the mouse first, then typing works.
Hint: using a shortcut to open the "Tag last untagged time" works better, typing is possible without mouseclick.
I think this should work ok on the latest versions.
