I am working in a theme based on Suite7, but with some changes, including the placement of the logo into the navbar, some changes in styles, i.e colors, and size of the buttons and boxes, that seems too loose or space-taking in the current Suite7. This theme is there for you to fork or to collaborate with it at:
The idea, is to include several administration options, in order to change some settings.
Besides, I contributed a theme based on SpecINFO_Blue, but with some elegant changes. This theme have already been merged into Github SuiteCRM master branch, thru a pull request, but not available yet with the zip distribution.
It is separated for you to fork and contribute to it thru pull requests.
All you have to do to test, is to put in /themes/, since there is no an installable yet, or if you will be developing from your instance, treat them as git submodules, using:
(from suitecrm directory in your server)
git submodule add email@example.com:bmya/TemaBMyA2.git themes/TemaBMyA2
