Is there a therapy session in the game to change sexual orientation (that isn't an item)? If not, that would be an interesting function to add to the centre.
On that note, I've noticed a lot of consumable items that could be made into functions.
For example:
-sessions to cure yandere/tsundere (though I think this is already part of the centre's therapy sessions?)
-Minor actions ("Put on a Show", "Give Out 'Samples' ", "Bondage Session", "The 'D' ") that could be turned into scripted options
-Certain transformative items such as Dar-E Pills could be made into a training-type job for the appropriate building
-Surgery items could be merged into the Clinic, either as separate Job Options or random results from surgery
-Execution (the "Execute" item) could be a separate button, similar to releasing or selling slaves
These are just a couple ideas I had, but it would be nice to see these implemented, if only to clean up the item list for shops a bit.
