I have looked through the hooks and cannot figure out which hook could provide a way to alter a form in the control panel (e.g. the create/edit member form or publish/edit entry form). I don't want to use the CSS/JS hooks because that's altering it client-side.
Is there a way to either:
- Grab the output prior to it being sent to the client
- (even better) Get the objects used to create those forms and alter them?
I also want my extension to be able to be called on every control panel page.
