[Plugin: Grid Archives] Event Calendar

Hi,
I’d like to use this cool archive plugin as a calendar to visualize events.
So I’m asking for some hacks to adapt this plugin or just to suggest new possible options.
(I’m trying to do it by myself but I’m not able enough with php)

Anyway
> I’d like to select which posts to show in the archive page (for example the ones belong to category “events”)
> To show the programmed posts too

thanks
