Dear developers team,
a lot of "things" have bettered in the last months in Thingiverse.
One thing I recognized, turned to the worse:
If I want to collect a thing and I'm opening "Select a Collection" only 20 of my 128 collections will shown up - the rest is lost
I can still manage all of my collections - but only 20 (I can not influence which one is shown up ?!) are visible in the "Select a Collection" section.
