I have attached screenshots of what i mean. You can see in Screenshot 1 that the tab T2 should be under the Idols parent tab. Let me know if i should provide anything else!
I’ve noticed this as well, but I assumed it was working as intended. I actually like that I can see all the tabs in the “normal” layout when I first open it so I can go right to a tab I need to if it’s on hand without changing categories.
If this isn’t as intended, maybe there could be an “All Tabs” category as well that serves the same purpose? Categories are great for organizing but sometimes it’s just convenient to not be filtered.
