Shredder Alpha 1 compatible

I have recieved requests to make my extensions support Shredder Alpha1 (TB3a1). However, I'm not plan to add Shredder a1 support. Shredder a1 is the initial version and it will be changed drastically. So, I will not add TB3 compatibility at least until TB3b1 is released.

Moreover, I don't decide whether Maximize Message Pane and Gmail IMAP Account Setup will support TB3 or not. TB3 will have a tab functionality, which will be a substitute for Maxmize Message Pane. TB3 also will support easy setup of Gmail IMAP. Do you need them despite TB3 has similar functionalities? Please let me hear your thoughts on them.
