Selecting notes by type

[Brollyy]

Idea from AbeVsTheWorld on Discord:

If there is a tool I would like to see in Edda is to select all specific types of runes of my choice so I can delete them for example. Reason why is when I make the map on a lower difficulty, I mostly delete the X runes. If a tool like that exists, that would save me a lot of time. I usually have to scroll the map and delete the Xs one by one. Kind of tedious to do. Get me? Not just the Xs too. Those squilly looking ones in the 1/4's beat.
