Its been there for many years: Like todays social media offerings the "Ideas-Portal" by Esri allows you to post ideas or "like" (here vote for) others ideas ... and thus give ffedback to Esri about wanted/needed features.
So first of all:
- If you have an idea or are in need of a feature ...
- Search for it - did anyone already post this request ..
- and if so - support it OR ...
- post it as your new idea!
- You now find the Ideas portal integrated into GeoNet - it has changed its place
GeoNet is something you should bookmark anyway: It's where the Esri Community meets (virtually)!
