Thank you for the bump, I missed your topic.
Since this week Buttonizer has a new User Interface, hopefully to make everything more clearer. If you go to the group/button settings, you'll find 'Position' in 'General'. If you change the percentage from
Horizontal from 5% to 0% it will be fully at the right side.
Unfortunately, it isn't possible to extend the width of Buttonizer labels yet (for full-screen size). We will work on this in the future. So I will keep you posted about that.
About the icon on the left. It is possible to mirrors the label. To make that happen you should set the vertical alignment to
100% instead of
0%. This will mirror the menu automatically.
Let me know if this helps!
