In #23546, I requested a separate 'Edit with IDLE x.y' (I mis-said 'Open') on the context menu for each installed version.  I said I would be OK with one 'Edit with IDLE' entry and a submenu, as proposed by someone else.  I agree that this will be better in the long run.  In the meanwhile, I have 'Edit with IDLE' which happens to be connected to 3.4 and 'Edit with IDLE >' with a submenu with 3.5, and no option to edit with 2.7.

Thijs: The editor is basically the same in the most recent 2.7, 3.4, and 3.5 versions. So it does not matter much which Python version is used to *edit*.  But it does matter which Python version is used to *run* the file with F5. And there are bug fixes in the next 3.4 version that will make editing easier for some people.  And there will be even more changes coming in future 2.7 and 3.5 releases.

Perhaps the submenu should give the full x.y.z release number, as Idle can have new or changed features in micro releases.
