Quipu is a simple Pinboard powered session manager.
I have too many tabs open. I struggle to keep them organised. I need a tool that allows me to save some bookmarks for later, in groups, but that doesn't require me to spend too much time curating them. I also want to have those sessions available quickly.
Quipu uses tags to organise bookmarks in tabbed pages and cards. A bookmark can appear in multiple pages and cards, if it is so tagged. Pages and cards provide no hierarchical structure, they are for the user's visual convenience only. Bookmarks are ordered according to when they were added.
