How to say it, it somewhat triggers me to see unfinished tasks lying around.

If it can be somewhat reasonably finished by armchair (e.g. this, by aerial imagery + a bit of thinking) then I will do it by armchair.

Sometimes it cannot be by armchair but can easily do irl-visit (e.g. various urban area notes). Then, I normally would shut and wait until someone else did it, or I somehow will go to that area and then look at them myself.

Your quoted note/4756215 is the case where it cannot be by armchair *and also* cannot easily irl-visit there.
