I'm new to using splits on 4K monitors, and with the configuration shown in the attached screenshot, I’ve run into a limitation with the current Monitor Selector.

Specifically, I can only send windows to regions 1 and 3 using the number keys. Pressing "2" doesn’t seem to have any effect. Also, when I press "1", the window is always sent to region 1.1 by default. To move a window into regions like 1.2, 1.3, 2.1, or 2.2, I still have to use the mouse.

Just an idea: it would be nice to "name" the splits and then use A–Z keys to indicate the destination monitor split.

Creating custom functions sounds really useful!
Can these functions be invoked directly via the CLI? If so, could you point me to a working demo where a custom function moves the current window to a specific monitor split — for example, split 2.3?

Also, I’m curious: how do these custom functions determine where to send the window? Are the destination splits identified based on how the splits are enumerated internally?

For context, I use multiple multi-monitor setups, and I’ve been using the same DisplayFusion profile/configuration across different computers. Would custom functions be able to adapt automatically to different monitor configurations?

Regarding the use of arrow keys to move windows — I’m not sure how this will be implemented, but I’d be interested in testing it out if it’s already available in the Beta version.
