Usually I have many swaps open and there for have to have on paper written notes of actions and this is starting to annoy me. One specific case of such action would be, when I have to pick out the coins, where the swap is actually agreed upon already. As I am kind of a busy with all sort of stuff, yes, I tend to forget for couple of days over some swaps, that need little to finish. But there is no marker on Numista, that could help me with that (except paper notes).
I would propose to add checkbox on each "Swap page" as noted below. Sole purpose of such marker is for users needs only and visible to him in overall "Swap monitor" page with specific sign, eg. exlamation mark as noted below.
Chkbox can be ticked out anytime user likes, or is automatically turned off when swap is cancelled or rated by both sides.
