Making good progress, albeit seemingly slow..
The biggest reason it is and will take a while is that it is a full and complete rewrite of the client (almost from scratch), converting it from Actionscript 2.0 to Actionscript 3.0. This offers a lot of new benefits, including speed, and file size, but also equally as important, more flexibility with features. Things like click and hold *should* be more possible in this version (don't hold me to it, I've not fully investigated that yet), but it does open the door for more fine precise control over various things. That said, it's a very time-consuming thing.
The result so far is very awesome, though I still have much left to do.
I'm hoping to be able to post some teaser screenshots soon.
Oh, and, tentatively, one of the planned features of this new version is the ability to order your inventory, and it should remember it between sessions (while on the same computer, for now.. ie, it'll be a local client cache, so if you switch machines, the order will be different.) This is subject to change, depending how frustrated I get with the rewrite process, but it is something I'm planning at this time.
(Hopefully pre-announcing this won't bite me in the rear.
No, there are no server issues with lag. The work I'm doing does not affect the servers in any way shape or form. I have had 0 lag here, and seen 0 problems on our internal network, so any issues are with the internet outside of my facility, and totally out of my control.
