Is there anyone who often uses "front-stage scheduling" like me? Does RectanglePro use any private api that can support tile mode for front-stage scheduling?

The problem is this, 1. I used Hammerspoon to write a window tiling mode, which is to tile all windows in the current space on the desktop in the best-looking way. When front-desk scheduling is not used, the effect is probably like this: ! (https://i.imgur.com/vq8pv73. gif) 2. But if front-stage scheduling is turned on, because front-stage scheduling can have multiple windows in the current group, I want to tile the windows in the current group, but I tried not to tile them according to the current group. Hammerspoon can only get all windows in the current space, but cannot get the windows of the current group scheduled in front of the stage. I checked github and said that Apple does not have this api; The result is something like this: ! [] (https://i.imgur.com/7Nuiy7P. gif) 3. Then I tried RectanglePro, and I found that this software can actually support the tiling of the current packet in the front-station scheduling, but only supports 2 by 2 or 2 by 3: !

I have bought RectanglePro, but I am still curious, and it only supports 2 by 2 or 2 by 3 tiles., not as supported as the one I made with Hammerspoon. If I knew how he obtained the windows in the group, I could change it myself. 😂
