yes, this is too late for 4.5, but as Ivan noted we can make this happen in 
4.6.

as for putting this into libplasma, that shouldn't be a problem. 
Plasma::RunnerManager does all the gathering and running of matches, so all 
the code can be put into RunnerManager without any API additions (unless we 
want to allow the application to configure how this works, but that should 
only require some binary compatible setters/getters).

if we want this to be available to other components (e.g. application launch 
interfaces such as lancelot and kickoff), then we'd have to export the API of 
AppStats ... but i don't think that really belongs in libplasma; that's more 
like KRecentDocument and perhaps belongs more in kfile or kdeui along with 
similar classes.

in any case, it's completely solvable.

personally, i would recommend implementing it first in KRunner if possible 
just to test out the ideas an ensure that they are workable before we commit 
to them in kdelibs where we then end up commited to them for many years.

btw, looking at the code, AppStats::score may benefit from QDateTime::daysTo.
