Hello, I am using the trackpad to snap windows left and right with BTT, but once I snap one left and one right, I cannot resize them both by grabbing the middle point. I need to do it manually by dragging each one to get the middle point drag feature
This is only for the macs "full screen tile" left+righ snap. Check from menu-bar almost on any app: Windows-Fullsreen TIle-Left or RIght. And in that mode you can adjust the way you described.
You can bound that functionality probably atleast via scripting. Or possibly defining it in macOS "keyboard shortcuts" and then it BTT using defining the trigger you want and shoosing just "send shortcut" (the one u configured.
btw. doesnt work on certain apps and not aware of how would get around that e.g. system settings etc. Most work. Trialled the second opt from above and seemed to work,
