Paths, polygons

Once I manage to match GEpro's view to an aerial photo, I select the polygon tool and trace the outline of a roof or floor. For a building, I might do the roof outline at a given elevation, then extend side to ground. This is great, as long as you don't care about sloped roofs. Surfaces may be horizontal or parallel to the ground; no 3D shapes. 

It would be nice if you could do ellipses and rectangles, in GEpro, without having to import from other aps. 

Why can't I drag more than one point at a time; how about dragging a whole polygon? 

How can I copy a polygon and paste it into a new location? 

EDIT to add: 

I can copy and paste pushpins and polygons among folders in "My Places" within my own GEpro. Is there a way to send those items so they can be pasted into someone else's GEpro? 

Last time my pooter crashed, I had to reinstall GEpro; I lost all my pushpins, polygons, etc. I can save names and coordinates of my locations, but it's a lot of time and effort to convert them back to what they were. Do I have to go to the coordinates and create a new bookmark, or whatever, there from scratch, after reinstalling? 

I have long suspected that I may have picked up malware with my GEpro. I would have dumped it and made sure to get a clean copy... but I would lose all my places, paths, etc. Unless there's a way to transfer that stuff to a new installation. 

Good questions and debates. These were spoken before. However, the GE AI has been kept simple for every level of users. Extra requirements have always been encouraged to be subject to developers. You know, there is no end for the demands though the application must be in a simplest form for simplest usage.
