I often use "ACL" smart-icon in workspace, but never used "Server call", "Disconnect". I've changed them as following:
2.Open "vwork.smi" by binary-editor. Change first 3 bytes from "&h43 &h53 &h48"("CSH") to "&h49 &h43 &h33"("IC3").
3.Restart Notes, and File-Preferences-SmartIcon.
4.You can see "V4 Workspace" set, and rearrange icons.
5.Save this one, changing name of set to "V4 Workspace0".
7.Reopen "vwork.smi" by binary-editor, restore first 3 bytes to "CSH", change "0""V4 Workspace0" to "...Workspace" & &h0.
8.Restart Notes, and you must see the new set of SmartIcons.
