revise the look of the wis2box-ui, for wis2box-instances with many datasets the "homepage" may become congested

From @scottylad501 :

_"WIS2box - suggestion - May need to revise the look of the front end because as you add more data sets the “home page” will become more and more congested, especially for regions using a shared node. Imagine 10 countries sending 15 data sets each."_
