I use MorphOS as mainsystem (even for my small company - do the most things, which are possible, in MOS -> rest in MacOS or Windows). IRSI is very usefull for me, even it's beta! Some features are leaking at moment, but will see what future brings.

The biggest wish for me is to drag&drop Emails to any other place (HD-folders) and back, like Outlook does.
So its very hard to archivate or sort mails to the purposes/assignments they belong.

Second wish:
Encrypted output of VCALENDAR and VCARD. It's a bit grinding to search in this textfiles for event dates and times.

Far away wish: Calendar implementation.....

IRIS an Wayfarer are excellent pieces of software - glad jacad does this!
