the ui vision window is very uncomfortable because it does not attach to the browser
I agree
and overlaps and to start a macro you need to open it,
You can avoid this already with the bookmark feature!
See here:
=> Did you try to use this feature yet? If no, please try it 
If you used it already and did not like it, please let me know why it did not work for you, so we can improve it further.
it would be much easier and convenient to have a mini window in the browser (toolbar) that allows minimal operations to manage macros , you would avoid having to open the ui vision window that overlaps in front of the screen and confuses.
I agree that would be nice, but the extension API from Chrome and Firefox do not allow this (or do you know any extension with such an UI? If yes, let us know).
We plan to do a complete UI refresh in the future, and ideas for it are very welcome.
