You can’t find a note in big Graph
In the beginning, Graph becomes great solution. But when your Vault grows over 1000 notes, Graph value is dropping. Of course, you see your Vault in general, but you can’t see current note in it. This is a problem for people (like me), who use the Graph as a metro map.
Color change is not enough.
Proposed solution
The current opened note should either flash, or be considerably bigger, than the other notes.
Current workaround (optional)
I use Persistent Graph plugin to fix general directions of the large notes. Then I look for associations to find note I just connected. Sometimes I need to quickly click between Note and Graph view, so note would blink.
