Limit for plug-in in notes side bar

Hi All,

I would like to know

1)what will the maximum limit for the plug-in’s that we can install in the notesside bar.

2)if we apply them through poilices using different catagories is there a limit?

  1. any trouble shooting steps to know why a plug-in is not deployed to the user’s?

4)Once deployed how can we unistall a plug-in automatically from user’s machine if we decide not to provide them that plug-in any more?

Thanks in advance.

Niharika.
