When is it taking inspiration from a competitor, and when is it theft? I'd like to know the general questions to ask myself when reviewing competing products in creation of my own.
(I'd be surprised if something similar wasn't already asked, but a search revealed nothing)
For Example:
Workflowy is an amazing tool, but it lacks a good deal of features I'd like to see. I'm making my own productivity tool and I'd like to include a number of main features in Workflowy in the new design (e.g. the 'zooming' into list items, hiding and showing sublists).
Part way through though, I started thinking that I may very well be stealing the very thing that makes Workflowy a great tool. On the other hand, I think that ignoring good innovations like these would hurt a developer's attempt at making the best tool in that category. Future users may think things like "Program B is wonderful, but it's a shame that it doesn't have this feature that Program A has".
