Suggestion: indicate that global hide filters are on

Love the global hide filters. But as DO is so complex, sometimes you forget that there's a filter in place. My suggestion is that if DO is currently displaying a folder tree or folder where global filters is hiding files, to indicate - somehow, somewhere - that filtering is taking place, just so the user knows that not all the files/folders are being displayed.

Perhaps there could be a badge on the end of a folder name (in a tree) or on the tab displaying the files in that folder.

For the file display, you can do this using the status bar.

The status bar shown there is now one of the built-in presets in the Preferences status bar editor.
