[Feature idea] additional view in UI

[mglowacki100]

Now, there is a vertical list of repos with preview on the right side.
The idea is to add additional view of repos, more like in Pinterest, namely grid instead of list. Preview could be done as popup window. In such way, it is much easier to scan for repos.
Views can be switched by button close to search field.
Slightly different approach: witdh of the list can be adjusted and when there is enough place to fit 2nd or or more columns, list automatically changes into grid.
