I am working on a few projects that are nearing 100 screens, and linking them starts to become a problem.

Here are a few things that I think might help the situation:

1. Use the artboards order from the side panel into the dropdown menu. I don't know how the order in the dropdown is created, maybe by time of creation of the artboard, but is certainly not by name. By doing this we can at least group the artboards and find them more easily.

2. Incorporating a search bar into the dropdown is kinda strange and confusing, so another solution for me is to take the whole functionality of the arrow dialog to side panel. This will also solve another problem - when you have buttons one beside another, sometimes it's difficult to pick the arrow of the selected button because the link of the button beside it is above it. The panel thing will solve this problem also because there will be another way to link the button.
