First of all congratulations of the release of Charts 8! Looks awesome!
Small improvement suggestion for your consideration, it would be useful (I think) to, when you select the appraoch for a runway, to have an option to see the constraints/waypoint approach data directly on the map. As example, on the RNAV Z 02 approach for MGGT, there is a constraint of 8000ft at GT564.
I leave it for Navigraph team’s consideration
