I don’t think so, as you pointed out, the contact form is used for tracking, and squarp have explicitly stated they don’t (routinely) monitor the forum.
I think, stronger interest, would be felt with more feature requests via the contact form.
… so definitely, Id advocate people send their ideas in, Squarp want your ideas/feedback.
the forum is great for fleshing out ideas / understanding whats already possible, a role the community can serve very well.
but ultimately, FRs should go direct to Squarp, they can see the bigger picture from all users, and see how things may (or may not) fit on a roadmap.
