I find that I need to edit a server action but am unsure if it will affect other pages that might use the same action. It would be useful to see which pages/locations are currently using or have linked that server action file.
Excellent idea.
What I normally do is search for the SC name and it will return all the files where its called from. Useful also to do a quick search and replace when I change the name of the SC.
Maybe you could have a direct access on click to make a search through your project files for that SC.
Adding constant scanning of files or more metadata files would decrease performance in the first case and would potentially get out of sync in the second. Specially if you resort to changing code outside of Wappler. I use VSC from time to time to do some tweaks here and there.
