So, i have maybe 30 - 40 currently active projects. These range from re-styling my home, writing essays, organising exhibitions at work, running budgets etc. Currently I use a combination of OmniFocus, iCal, folders, Mail. OmniFocus is great for my task lists but I'm looking for an app that would allow me to see, for each project, all the relevant source material: pdfs, docs, images, etc Any suggestions ???
