Re: [PHPiCalendar-DEV] folding and unfolding

[Chad <ch...@ch...>]

Since Jared and I don't have access to Moz Calendar (though I could I 
suppose) we hadn't planned support until 0.9 or so. My thoughts are 
that adapting the parser would be pretty simple once we had gotten all 
the logic down.

If I have some time tonight I'll look at putting my PC back together. 
We can make mozilla the top item for 0.8.

In the meantime I'd prefer us stick to the roadmap for the next 
release. I'd like to have it out by sunday night. Although I think I've 
lost Jared's help to homework. ;-)

I'm sure the roadmap is somewheres in the mailing list archives.
