In the same way desktop IDEs do, it would be nice to have a clickable list of functions (including server callable) and class definitions, which when clicked take us to them.
I’ve got projects with many modules and it can sometimes be an exercise in brute force to find what I’m looking for.
As a workaround, for apps of that size, I use Anvil’s Git integration, to get a local copy of all the app’s files. Then I apply a smart editor or IDE (or grep) to my local copies, for such lookups.
Of course, such lookups aren’t literally inside the IDE. It’s more useful for reference, in its own window, while editing something else in the IDE. And you may need to frequently Save (in the IDE) and then git pull (on the PC), lest you end up grepping stale code…
The latter is, alas, mostly noise (to me). But the former distills critical information in a useful format. I’d trade for the function listing any day.
