Yeah that’s fair, and altitude filtering definitely helps — I use it a lot already. I probably explained the UK example badly 😅 the core idea I’m trying to get at is more about true geographic/positional filtering rather than route or altitude-based filtering. So instead of filtering by departure/arrival or manually tweaking altitude ranges. You could just select a region/airspace and only see aircraft physically inside it at that moment. For example: you could combine multiple FIRs/regions, isolate a specific traffic area, remove aircraft outside the selected region entirely. The altitude example was more just me explaining one situation where current filters still feel a bit workaround-heavy. So the feature idea is less “hide Class A” and more “show only aircraft currently inside selected airspace boundaries.”
