Would love to see reporting, tracked from the Retool server side, for app usage. Button presses, dropdown changes, tab changes - basically all interactions. This would help us to measure how the apps are being used, which features could be potentially deprecated, etc.
Server-side, because I'm assuming the data is already all sent through your side. And then we would not need to add in additional client-side tracking which is a pain to create all the events for.
For the reporting, it could be a simple breakdown of interactions (and maybe values, if you want to go the extra mile) for each component. Filtered by date range.
(so separate from Analytics for Public Pages)
