Looking through the app, it looks well crafted but not so compelling in the UI. Anyway, i've been looking into many project management tools with a Gantt chart approach and i think this is what i need. A few options should be more accesible like user assignations and activities registrations. The collaborative approach is pretty cool and save/undo actions are really useful to create a draft planning. I will follow this app closely.
Thanks for the feedback! UI improvement is definitively our top ongoing effort. Other features such as external links and printing are planned as well for our next release.
