Instead of Overpass Turbo
The mean feature of meshmixer is review and ability to modify and remix meshed models like for 3D print. I don't see many listed alternatives here have that workflow easy for users.
Two feature that make it standing. It does support: Dual subtitles display simultaneously with MPlayer Engine. Auto loaded EDL with MPV engine (Family watch blessing).
It is well designed. It accepts donation from anywhere. But receive is limited to only 44 countries.
