Hi everyone,
While I tried to learn how to implement custom blueprint nodes via C++, I thought that it would be nice to have something like a managing tool for Unreal’s Gameplay Tags.
Thus, and out of curiosity about UE4’s Widgets, I set out to create such a tool.
It’s far from completion (e. g. most of the GUI isn’t finished by now), but most of the important stuff is already implemented. Since I’m a beginner I’d really appreciate if you’d help me by trying it out and giving me some advice.
Thanks in advance! 
Note: I recommend you to create a shortcut to your desktop and start the program with the “-windowed” argument.
Oh, and I’ve attached a txt-file that shows how your gameplay tags may look like.
