I have installed and removed FO about 10 times, every time thinking I missed something just to find out that I can't get past the first few days of use.
So I spent the last few weeks looking at alternatives to fengoffice and trying to better understand what's that bottleneck that seems to be blocking me to use FO and I found it: customization
I can't even report on custom properties!
Sure I can list them, but not make totals, let alone any other form of analysis. There is no currency field, no cascading, not even calculated fields!!
Not to mention make/modify modules (applications).
The only thing I can do is use it as it is: An arrogant approach, in my point of view.
So I have installed and tried a number of web apps, Tine20 and SugarCRM just to mention but a few and they ALL provide ways to customize/add core modules. As a result their communities are much more active in providing plugins, new modules, themes, and all it is needed to really get them projected into fast development.
Conrado:
have a look at tine20 they will leave FO in the dust if you don't move fast.
I'm looking forward to seeing a definitive change of course.
