just wanted to run this to you (or whoever's interested) step-by-step to get keyclone to add windows without having the option in Keyclone -> Setup -> General -> "auto-add windows titled" enabled/checked.

Keyclone -> Setup -> Command Editor

command can be anything you want to name it. so for 4 accounts, you'll end up having 4 commands. i name mine as wow1, wow2, etc.
program opens up a browser that you must point to wow.exe. this is very useful for when you have different folders for different instances of wow.exe as in when you have multiple or symlinked \World of Warcraft\ directories for different wow characters/instances/accounts/whathaveyou.
keymap opens up a browswer that you must point to the keymap (eg wow1.kcl) of this WoW instance. a keymap can be created through the keymap editor and is basically a hotkey interpreter. you can ignore this if you just want keyclone to send the same keypress to all four WoW windows.
region refers to the name of the area that you setup for this WoW instance in Keyclone -> Setup -> Maximizer. if you set Maximizer to divide your screen into four section (coz you have four accounts going by the earlier example), then you'd put in the name of the top left section in Maximizer in region.
wow: username is the username for this WoW account that you're setting up a command for.
wow: maxfpsbk translates to this WoW window's allowed maximum frames per second when it is in the background.
maxfps on the other hand, is the allowed maximum frames per second when it is in the foreground or when it is the active window.
bring-to-top-hotkey is self-explanatory. useful for when you have all four wow windows stacked on top of each other instead of having your screen divided into four sections. so for this example, we won't have it enabled.
always on top enable to make it on top of other windows. useful for overlapped PiP (picture-in-picture) regions. we won't need it for this example since we don't have any of the four sections overlapping.
lock-in-foreground was designed for other games.
exclude from RoundRobin when you have a round-robin key setup, enabling this would make it so that the nominated round-robin key will always be pressed for this WoW instance.
receive-only enable to get this WoW instance to not send keypresses to other windows whenever it is the active window. it's kinda like having override always on for this window.

when you've filled all of that out, press the "+" (plus) button on the bottom right hand side of this window which is right above the cancel button. doing this will add it onto the "command" column on the left hand side. do this three more times for the other three accounts using the appropriate information where necessary. and hit OK to go back to the main Keyclone window.

to be able to use the "commands" that we've setup, type in "wow1; wow2; wow3; wow4" on the input field at the bottom, then click "connect". the WoW windows should now launch appropriately where you've set them up to be in Maximizer along with their account names already automatically typed in (if you've set it up this way). hope this helps
