I'm trying to find some sort of all in one tool that would allow for as many of these as possible: -wireframing -testable prototyping -managing feature backlog I've tried adobe XD and for UI it's nice but I want to focus on UX/wireframing more than how it looks exactly.
I don't really know what I'm doing entirely for overall workflow so if people have processes/workflows they can suggest I'm also open to that.
The only thing that most prototyping tools add (IMHO) is better organization, more rich interaction and some premade graphics, but if you don't spend all day prototyping I think Powerpoint (or OpenOffice) is just fine. Task management / feature planning shouldn't be done in the prototyping tool IMO.
Other than that: Pen and paper.
