There’s nothing like moving back to Lotus Notes mail after using another mail client to highlight some omissions in functionality or irritations in client behaviour.
The issue with Domino 8.5 IMAP has caused me to do just that – to move back from Mail.app/iCal (my client of choice, given my MacbookPro/iPhone combo and use of OmniFocus for GTD) to Lotus Notes 8.5 (which I’ve still been using for application use – especially blog management). Suddenly things that I’ve worked around for years in Notes stand out…
So, a couple of ideas on IdeaJam, and there will probably be more over the next few days!
