Yes, I think we could do with a bit more detail on the alleged offence.
I agree absolutely with your point. The challenge is to design a UI
that makes Good Stuff easy and Bad Stuff hard! Potlatch tries to do
this by "hiding" the one destructive action exposed to users -
deleting ways - by requiring you to Shift-Delete. (That seems to work
by the number of people on IRC who ask "how do you delete a way in
Potlatch?" :) ) If you click a way and press Delete it will do nothing.
Brief digression - there did use to be one issue with merging ways
where you could accidentally delete a way:
- User merges two ways
(Potlatch does what you'd expect: adds way B to way A, deletes way A)
- User thinks "I've changed my mind, I didn't mean to do that"
- User presses Esc to revert
(Potlatch reloads last saved version of way A)
- Result is that way B is "gone" (though still in history, of course)
That was fixed the other week. Now, Potlatch makes a little note
internally that "way A had way B merged into it", so when you press
Esc to revert, it reloads both A and B. So that one's closed.
The undelete/revert stuff is potentially really froody. If someone
tests it this morning it can go live this afternoon.

Thanks!
