All is well here. Just a lot of working at home, walking the dog, and going for a long drive every once in awhile.
Inline lists won’t work with Favorites because an inline list will not show the Favorites selection above the list. The only way they work is when you have a tab style set to List.
Basically you would have to build your own version of favorites to get around this. It’s not an easy process to explain, but for starters, you would need a form button to submit a unique ID or some value to a sheet, along with the user’s email. Then on some page that has user specific data filtered by signed in user, you would need to create a relation from the user’s email in that sheet to the form response sheet. With all of those changes you could add a choice component in the horizontal layout to simulate the favorites choice. This is a very rough explanation and doesn’t fit well with the Instagram template without quite a few changes.
There is a feature that Glide is working on that would make a lot of this quite a bit easier, but it’s not available yet.
Take a look at The Dynamic List Filter in https://concepts.glideapp.io/ along with some of the other examples to see some of the things I’ve done. Also look at the Food/Activities tab in https://rwtsk.glideapp.io/ to get a rough idea of what I’m talking about.
It’s really hard to give a definitive answer since so much would be involved at this point to make it work.
