I try it again:
The functionality I need the most is to arrange, sort, group the entirety of all citations, ideas, notes, fragments (related to one project/publication) within one tool. My hope was that zettlr would be the solution (apart from providing a markup environment, a clean GUI and a citation machinery which for me are nice-to-haves).
As I understand it (am I wrong?) searches for keywords are zettlrs method to group or to associate the relevant objects with another and to make this visible to the user. Now I wonder whether I can make my zotero annotations and notes part of such a search in zettlr (if my zotero bibliography is connected to / imported in zettlr?)
If not, isn't the idea of zettlr's zettelkasten flawed? It would look to me like a car with only two wheels (which isn't that much of a car). Am I missing something?
(My online search showed some german universities promote the use of zettlr. Unfortunatly here in my town (Aachen) zettlr is unknown even in the university's informations department where I asked to find someone who would help me to get a grip of zettlr against payment. And note: I build and administer my HW and SW since about 30 years, so I claim not to be inept in computer and SW related things).
And at least take my questions as a feedback. If you like to expand the number of users I'd really recommend to provide exhaustive examples. As much as your documetation helps some users, you (in my opinion) lose more users then you reach. For me your documentation shows many trees but no wood. I am stating this with all my respect for your work and with a desire and an urgency to find a SW which fits my needs.
The point of good examples would consist in being as self-explanatory as possible. Or at least a start to get an overview.
Thanks for your attention.
