"Development Status" seems to be incorrect
Sorry, guys, but as of version 1.1 the status is nowhere near "Production/Stable" - when trying to go through the basic workcycle, I've encountered 2 showstopper bugs, one of them (attempt to fetch project_id from empty activities list) required code modification to continue, another one (possibility to assign activities to invoices) seems to be just plain abscent and inaccessible from the interface (though it seems to be present in the code), so I just had no possibility to generate invoice.
I liked the whole logical design, though - assuming that the application works at least minimally, I will certainly try to use it for time tracking in small projects.
