The moving and resizing with mouse modifier functionality gets me almost all the way to my workflow with plasma on linux or ahk on windows. The last bit of missing sauce is how windows resize for the resize bit of the equation. It would be super cool if the position of the cursor within the target window determined the direction of the resize.
I don't know if the coordinate system in the window manager allows resizing from anywhere but the bottom right, so resizing from the top or left may be a combined move and resize. To hopefully clarify, here's a table of cursor locations within the bounds of a a window, a movement, the resulting change, and the point of change (hope gh markdown works here):
|Cursor Location||Cursor Move||Change||Point of Change|
|Left Half||Left||Increase Width||Left Side|
|Left Half||Right||Decrease Width||Left Side|
|Top Half||Up||Increase Height||Top Side|
|Top Half||Down||Decrease Height||Top Side|
|Right Half||Left||Decrease Width||Right Side|
|Right Half||Right||Increase Width||Right Side|
|Bottom Half||Up||Decrease Width||Bottom Side|
|Bottom Half||Down||Increase Width||Bottom Side|
Thank you for including mouse+modifier window movement and resize, and thank you for giving me three-finger tap as middle click for opening links in new tabs!
