foundryvtt-gmScreen VS gm-notes

Not sure what is going on. I downloaded this file https://github.com/ElfFriend-DnD/foundryvtt-gmScreen/files/10094884/gm-screen-final-pre-release.zip unzipped, restarted and enabled. Did you check the permission on the folder you moved to $foundry_data/Data/Modules and make sure the foundry instance can read it?

It's a great module but I don't think it will be updated. See this: https://github.com/ElfFriend-DnD/foundryvtt-gmScreen/issues/130

For anyone interested, here's the project status statement saying that there is unlikely to be a v10 version of the module: https://github.com/ElfFriend-DnD/foundryvtt-gmScreen/issues/130. Of note is that part of the reason for the module being deprecated is that the APIs it uses changed drastically, so taking over maintainership would be less of an update and more of a rewrite.

GM Screen - gives you a GM screen with your custom info.

GM Screen

Bonus: Using the module GM Screen, you can add this journal entry into a pop-up screen that players have access to. It makes it much quicker to use than having to open and close a journal entry multiple times.

GM Notes has done well for me. Lets you add a little pinned text box to any object that only the GM can see (button for it's up at the top of the relevant object window)

check GM Notes, its compatible with 9.x

The GM Notes module adds a special notes section to actors, items and more. It doesn't pop them out automatically though. You still need to go into the actor's sheet.

I use the GM notes module (https://github.com/syl3r86/gm-notes). It adds a new tab to all entities like actors, journal entries, items and so on where the GM can write notes which are visible only to himself
