i have a problem i can not find a solution.
In the organization of my knowledges (and only knowledges, no stuff like "to do"), i need a way of sorting my stuff with lots of levels, i mean
Notebooks NOR tags allow me to set up my stuff with lots of levels as i need : both only accept 2 levels, but i need something deeper.
Hope i'am understandable :-)
Any ideas/tips how i could build something like that?
any help appreciated.
