Make backup for new&updated user apps only

[thany]

I don't want to backup system apps. There's no need for that. I also don't want to backup apps that haven't changed since the last backup. Unfortunately, the "Show only users apps" filter doesn't work right. I can't show a combination of only user apps AND new&updated apps. Which should mean: only new&updated user apps.

I thought I could workaround this by "select all" while the "new&udated apps" filter is active, and then "deselect all" while the "only system apps" is active. But unfortunately, the "(de)select all" function appears to apply to the entire collection of apps, instead of the visible collection.

Can you make this possible please?

I'm on version 0.3.5-universal from F-droid, on Android 8.1.
