Yes, something similar or exactly like that. I recently discovered the 'quick new point' tool which already helps me tremendously. If this tool would be extended with more fields and options like importing files or editing the memory of this tool, this would be great. Also adding information to lines or polygons would be my wish and I suspect that the proposed 'open data kit' in the former mail could help with that. Also, right now, I dont think Locus has any way of handling polygons. It converts .kmz polygons to tracks anyway.

...forgot to mention.... already the possibility to appoint different specifications or icons in the 'quick new point' tool to different poi-categories separately, would improve this tool greatly!
