Tags - view, search, number

I’m a newbie regarding Tropy, so excuse me if this was already mentioned somewhere. I have tried to find a similar topic.
So my request would be to add a new View screen where we could list tags in some sort as a popular tags cloud. Also, with numbers of how many items are listed under one tag. Tags should also be searchable. For example, if I add tags like food, drinks or house to several images right now, I can not search tags in the search window. If I have food in the title, it will show it, but not if it is only used as a tag.
