Could you possibly add the abiltiy to add your own values for certain tweaks in a future verson Ex. The menu delay/Time to kill process etc... I currently have a reg file to do all that but it maybe handy for others who dont know about it to beable to set different values according to there preference.

You can make an addon and simply add your tweaks into the entries.ini file.

But it doesn't accept the reg format, just INF. For REG you can use the Unattended - Runonce and add "regedit /s %source\example\file.reg"

Hint: see in the help of that page how to use %source%.
