Where to feedback on Insider Build improvements / feature requests?

Is this still the right forum for feature requests if they are only relevant to an Insider Build?

It’s a simple one regarding mapping table row moves to the existing line moves hot key arrangement…

Yup, the Feature Requests category on the forum here is the place. The usual: search before posting, one FR per topic, and follow the template.

There’s also the #insider-desktop channel on Discord that’s always active around new insider build releases, but feature requests should go here.
