Possibility to hide connections or add styling to it

[gergokee]

We have 70+ connections and the redis commander ui is useless cause the connections tab is taking up the whole space. We either need a solution to hide the connections or add for example max-height:100px; overflow:scroll to connectionsBar to make it be able to be used even with many connections.
And maybe also add the possibility to resize by default too :)

Hi, yes sound reasonable.
Feel free to add a PR to hide it. It should be configurable with default value visible. Than i can approve it.
I do not have any time to implement it in near future atm.
