Thank you for taking the time to post these screenshots.
The search issue is a major bug that I am working to fix for the next release.
It would be hard to explain, but the alignment of those buttons is an imperfection that there is no elegant fix for. If your screen were a few pixels wider, the buttons would be aligned in a straight row. If your screen was maybe 100 pixels thinner the “Add User” button would drop down onto its own row. I could make the button drop down sooner but it is better to have to scroll less. I hope this makes sense!
