Hello! First post on the forums, so apologies if this is off in any way!
Been using Unreal Engine for a few years now, it’s really an amazing engine. One of the biggest revelations I ever had at some point was finding out you could place certain nodes with certain hotkeys. I know it seems like a super tiny thing… and frankly, okay, to be fair, you’re right. This is a very tiny feature request after all…
But in terms of development pipeline, small little quality of life changes can go a long way to saving time. Even if just a tiny bit. You know how you can press “B” to place a branch node automatically? My request is to have something like that, but for the “Is Valid” node! I think a lot of people can relate that that is a very commonly used node (at least for those that use blueprints) as its used for… y’know, all sorts of very important checks and whatnot. Optimization. Blah blah blah. The whole shebang.
So, to make a very long suggestion short: you should be able to press “V” to place an “Is Valid” node! I think that’d be super helpful and something a lot of people would like. Maybe. So sorry, I know this is like, a super small tiny little thing. Probably not even worth suggesting. But I just thought it’d be a super cool neat little quality of life thing 
(also, if I did anything wrong in the posting of this - like, wrong section or wrong tag or what have you, please let me know and I sincerely apologize!)
