OK, I've just encounter a problem which I expected:
RotateHomePlugin.sh3p is inside of a zip archive in dist folder.
Plugin Manager downloaded the archive, delete my current installation but than it don't know what to do next.
For me is not necessarily a problem, I could fix it for me but than I have to pay attention to not update it again.

So, I suggest to have a minimal set of rules in make and publish plugin:
- usually the source code are included in sh3p but if not, have to be published in two separate files(sh3p AND zip).
Normal users need only sh3p.
- some rules about license files and README file(s).
- maybe to include also a CHANGE LOG file which could be translated

Are only few suggestions and I expect more.
