[feature request] - allow creating macros in the assign key modal

[deviantfero]

I think since both UI instances are a modal, it should be possible to add this feature, reducing the time one spends navigating from one feature to the other, let me know what you think, if I get the chance I'd consider implementing it myself.

EDIT: thank you for putting together this project BTW makes using the vortex core so much better and effortless :)!
