Controller feature update suggestion: adjustable unit heal health (at what ratio of the units health should it retreat to heal); this could be similar in implementation to the range adjusters. However, when the units are not fighting, they should still head back to heal to full hp first.

One QOL update that would be nice is touchscreen button labeling (if you can fit it), and some operational stats on a traditional message block or on separate screen if you want.

This is by far the best unit controller out there on the WS, one other feature that would be a nice extension to the new unit defense point feature is unit patrol points and/or maybe multiple defense points to spread units out in a wall formation. Ofc doing this would warrant unit communication of enemy positions between them (vision sharing), so in addition to that a turret radar functionally could also be useful for redundancy and reliability.

I recently made modifications to your old unit controller that added "unit vision sharing" and "turret radar" for personal use, let me know if you would find it useful as a guide for building a new update.
