my sugestions:
1- Skins system to modify interface (it could be compatible with VLC Skins)
2- Emoticons in images (equal to imgmirc.dll, but custom size of images in width and height)
3- add toolbar treebar trackbar and progressbar native of mirc for add in dialogs
4- dock any dialogs in any windows (without getting over the messages or nicknames in the nicklist)
