Right now Database collections are displayed in the sequence which they are created. Once the App get big it becomes very difficult to find the collection and it really affects the productivity. Its just a simple feature that I think Adalo can easily do it.
It's actually arranged alphabetically where I have to use some kind of relation but then why not in the main Database collections area??
In the images you can see there are lot of Database collection and its painful to find a specific one easily.
