I'd like to put a suggestion in the box:
It would really be great if you standardized your file structures in all your plugins so it's consistent and also cuts out steps for installing. Whilst your plugins are all awesome, they are much more laborious to install than normal plugins (even manually). whilst one plugin update is easy, it gets pretty tiring when updating/installing even 10 plugins.
Two things would help
1. remove the update notifications plugin so if we unzip a plugin, we don't have to unzip a second file. the notifications plugin is a plugin in your own repo anyway.
2. Maybe you have a specific reason for this, but why not do it the same way as wordpress plugins? By that I mean if you unzip this plugin, just move the contents to the right folder. I envisage a folder and a php file (which is used to include the right files within the folder if used in mu-plugins, otherwise not used in plugins)
That would make life that little bit easier (I imagine for you too?)!
