While generally, I think this is a nice little addition, I would recommend putting this in a third-party extension as this component is fairly extensible.

The reason being that some communities might don't wanna show the total vote count by default or already show the total vote count before voting etc.

Not really for nor against this PR. Opinions @imorland ?

[gianniguida]

Or I can add a setting to toggle it on and off...

[DavideIadeluca]

Yeah that would certainly be a possibility, but that also means more long term maintenance and complexity added here. To be honest the permissions/settings handling in polls is already a mess and unintuitive to use so I would hold back with that.

Nice work @gianniguida - I don't see a problem with this at all 👍
