As a further idea I wonder if it could be made modular?
So that the base would be sparse (like above but with an address bar with basic navigation buttons)
with other add on scripts to add link hinting, cookie handling, history, bookmarks (with a use dropbox to sync feature?)
with a 'task-pclosbrowser' for a full featured version, or add what you need...
I am not sure how ambitious i am with that idea though
I am drawing inspiration from luakit
