I'm working on https://github.com/drawdb-io/drawdb trying to optimize the editor and have it lag less when the number of tables increases. Also have some highly requested features I'd like to implement before launching on Product Hunt.

Then I wanted a change of pace and started on something so ambitious that it's stupid... I'm trying to make a web browser from scratch I guess. So far tokenizing the html is going fine but I'm not sure how far I'll be able to get.
