To recap from our previous discussion, my 3 requests are, in this order:
Ability to reorder windows/tab groups. You mentioned you'd get to that when you have time. Thanks! This is particularly important because I will use the app to store tab groups/windows because I currently have 30 windows open with 10-30 tabs each and it's slowing down Safari. So I'd like to save a session, rename and reorder the tab groups/windows, then close the windows in my current session of Safari. When I need them, I'll go back to SessionRestore and relaunch a given tab group/window.
Add undo (Command + Z) when combining windows/tab groups for example. It would be nice if it functioned on all app actions.
iOS/iPadOS app! That would be amazing to sync these tab groups!
If those three things were added, I think the app would be nearly perfect!
Another item if you feel it's worthy:
Lock left panel SessionRestore session window. It scrolls in all directions.
I have tried multiple apps for restoring and saving sessions and this is clearly the most advanced solution!
I am sorry. It is not your app fault, because all extensions box are not able to tick.
Is this happening while you're using macOS Catalina? If so, it's a known bug in Safari, apparently introduced in Catalina v10.15.3, which has been very thoroughly documented by solo developer Jeff Johnson, and mentioned by many others, including Michael Tsai and Rob Griffiths. As far I'm aware, the bug has still not been fixed as of Sept 2020. In late July, Apple did at least acknowledge the problem by posting a brief support article that merely suggests rebooting your Mac in "safe mode" in order to enable your Safari extensions, then rebooting normally.
