Great timing since I am presently in the throes of switching mail clients.

I have TBat and TBird and have been making a comparison. I also have been working with Barca 2 (Pocomail 4 mail engine). Once 25,000+ e-mails just "disappeared" without a trace! I couldn't even find the folders they were in,
but next restart and Abracadabra!

they were all back AFAICT! I really like a lot about the way the Pocomail client works, but this type of "magic" leaves me less than confident, but I digress. </hijack>
I used TBat for some years until about ver 3.90(?) when Ritlabs removed using the Space Bar to read the next unread messages.

Fortunately they added it back in one of the latest builds.
In light of your post I have a some of things I would like to know about the "new" TBat.
- Did Rilabs stay with the method of not loading HTML in-line remote images in the body (images that load in the e-mail after it is opened that are not part of the mail you received) or have they finally allowed the user to make the decision?
- Did Rilabs make it an option to allow image attachments to be viewed in the same window(tab) as the text as opposed to the present click-on-the-other-tab-to-see-your-picture method?
- Did Ritlabs make any improvements to the SmartBat (Scheduler and Notes)? This isn't critical, but both could be less arcane.
Thank you for the heads-up!
