Do plugin also works in Roblox Player (in live builds)

Hi members,
Do plugins also works in live builds? Like, giving developers Studio Widget to insert some data. Now on the basis of this data, can plugin works in running build? Like spawning of refered models, Show Own Gui, Firing Events that could be listen in Server OR Client side, etc.
Basically making the tasks easier for the other developers. They would just need to listen these events and fire to tell the option chosen by the player.

As far as I know, no. Plugins only work in studio – you’d have to write your own code for doing such, but it would come with much more advantages as you could control what all you want it to do and grant permissions to specific users.
