a simple plugins that the admin/op cand change or remove the push limit on pistions this could allow for pushing/pulling of mulit blocks with sticky-pistions? config may look like this #pushlimit default is on, if set off theres no push limit will be set max 1-50 #pushlimitset allows for you to set a max push limit for the pistions pushlimit: on pushlimitset: 13 #stickypiston on by deafult if set off you can set the max block to stick to max 1-10 stickypiston: on sticky: 1 no love for this or can it just not be done?

Wow, I thought there was no way to make the sticky piston push/pull more than one block. This is me with a major 'do want'.
I would think both would be hardcoded, and fairly difficult to change. You could simulate it by listen for an event and moving than the blocks, but there probably would be problems with two blocks sized objects like doors/beds and even pistons.
Don't think it's possible, the values are harcoded (checked it for push a while ago) and the blocklist of the piston events are immutable.
