Ability to cross link items, to provide wiki like ability.
I use zim-Wiki to store pages of Information, that are cross linked to each other.
My wiki is stored on Google drive.(each page is a plain text note)
My moo.do mirrors the category's structure from my wiki.
When any item in moo.do needs in-depth information, I link it to the appropriate text file from my wiki (on Google drive)
Life is beautiful.
Now all that's needed is wiki like linking in moo.do and my knowledge structure mapping system is complete :)
Thank you for this beautiful piece of software.
