From paragonid :
"Everything from ~lessclicks including ~easymove is strictly clientside and relatevely simple to introduce on any server. I would take 3-6 hours for a developer to write it from a scratch. The code I wrote for it has dependencies on env though, and I'm not interested to re-implement stand alone version but can explain principle or even share it unless Cirn0 is against it.
Some of the stuff from hold shooting is server related and harder to implement, although as far as I know other servers in general has less attack actions and dependencies. Can explain principle if someine is interested."
