I have implemented the latest greats from Microsoft: the MVC3 still in beta and the Razor view engine and migrated into VS 2010 in the latest release. Must say, it's pretty sweet. Love the syntax.
Within the release, I have also added some kind of theme file manager, so you can edit your themes on the server. Not really a full blown file manager, but it does the job.
I have been developing newer version of the CMS so fast that if I did any type of documentations, it would probably be obsolete in a few weeks.. still the CMS is not where I want it to be, but I am pretty happy with the latest version. With very little it allows me to do a lot, which is the basic philosophy of this CMS. So promise, I will get to some docs hopefully soon...
I believe the Czech republic has the highest concentration of CMSes per capita. Just found out that one of the biggest ASP.NET CMS companies: www.kentico.com is Czech. How surprising :). Also www.webnode.com which is one of the big players in hosted CMSes is Czech.
When talking to my friend developers back home, it sounds like everybody has their own CMS, even one man webdesign shops do. What's surprising is that most of them are actually decent.
I am still trying to figure out why, but I think it has something to do with the Czechs being perfections about UI presentation. So any CMS is just not good enough. We want something that will produce the exact HTML/CSS we want, and will not settle down for anything else. Since HTML/CSS is very interpretative the demands are different, and so are the requirements for CMS.
