Currently there is no way to see how many ideas are being worked upon, things anyone is investigating? Engagment from community won't survive if you dont amke the information clear and start showing it back to the community. Right now the ideas section has no meaning as I hardly see any engagement from Mendix team even on top posts, this should be important as part of listening to its users. There should be a community manager who takes responsbilities of this ideas and priortises atleast one idea per release.
The engagement in ideas section has alerady dropped and would be soon non-existent if it continues.
