Drupal is a very powerful cms. Thanks for the advice. It's good that this company provides ongoing and 24/7 support services. There are times when I work even at night. In my case it is very convenient when I can solve the issue and technical fault at any time of the day.

For support and maintenance services Drupal, I would recommend contacting Attico drupal support team https://attico.io/services/maintenance-and-support. They offer tailored solutions for managing Drupal sites, ensuring you have the right support when you need it. Their expertise can help streamline your processes and enhance your site's functionality.

Who would have thought that Victor would not only understand the topic very well and contribute a lot with his comment, but would also share an excellent company that is especially dedicated to this type of work? Anyone who was looking for a company that offers these services should listen to Victor. His recommendation is really very good.

I am looking for the same thing as Diana, I need a company that can provide me with a maintenance service for exactly the same thing. I got tired of asking in several publications and nobody knows anything about it or they simply don't respond. I hope the same thing doesn't happen here and we can really get an answer, both Diana and I. Who can help us?

That sounds like an incredible way to turn GoodNotes into a true knowledge management powerhouse! Connecting keywords across all notes and instantly accessing related content would be a game-changer for research and organization. Speaking of structured knowledge, I’m curious—when it comes to managing and maintaining a Drupal site, what’s your go-to approach? Any must-have support or maintenance services you’d recommend?

It would be cool to be able to import mind-maps from external applications like SimpleMind or xMind to be able to annotate them in GoodNotes and attach to the library.

Should think about taxonomies l'île in drupal... Really power full

A good specification is really quite complex. ;-) Here is an addon to my request:

1. The folders are not necessary. They would be nice, but they can, however, be implemented later. Thus, for a first approach, each shelf would be a keyword group (as listed in a previous comment).

2. On the navigation via keywords / tags:
- For each keyword group there should be a list of all occurences. This list should be sorted firstly according to the note name and secondly (if its the same note) according to the page numbers within this note.
- One should be able to open the list for an arbitrary keyword and jump from there to the respective location in the notes, only by clicking the respective entry.
- It should also be possible to jump from a keyword mark within a note to the list and then from the list to another location (within the same or another note), where the same keyword is used.

I'm still thinking about the details:

1. It should also be possible to assign keywords to whole notes (pdfs).
Then, this request could would also include the request:
Assign tags (keywords) to a notebook and/or to a page

2. I've thought about organizing the keywords. Organizing them in mindmaps or hierarchical list would be nice, but I think that this is not necessary for the first implementation. I think, that the first implementation would be sufficient, if one could attach keywords (tags) at each position within a note and at whole notes. Then it should be possible to get a list of all keywords (tags) and for each such keyword (tag) a list of all occurences within all notes of the whole keyword group. This could be similar to the search feature, but not only within one document, but spanning all documents within a keyword group.

I think, that the implementation effort should be quite moderate, but the impact of such a feature could be huge, since GoodNotes would turn from a sole NoteApp - which is already really cool - to a knowledge management tool.

I forgot two important aspects with respect to this feature request:

1. Obviously, when one wants to assign a keyword within a note (pdf), one should get a list of already available keywords. Then, one can select one or create another one.

2. There should be subfolders, as is suggested in another project. However, this request requires one speciality: There have to be shelves (as they are already) and folders (subfolder, subsubfolder, ...) within each shelf. This is important! Then, one has _one_ set of keyword for each shelf (with all its folders, subfolders, ...).
Another possibility was, to have only folders (subfolders, subsubfolders, ...) and no more shelves. Then, there would be more flexibility. In this case, one should be able to assign, which folders (under which defined root folder - which has only the root property with respect to the keywords, but not with respect to the folder structure!) share a set of keywords.
In each case, one has a (set of) mindmaps or hierarchical lists for each set of
keywords.
I personally think, that the first variant is easier, but in this case, one has
to live with shelves and folders (within a shelf) at the same time. But this wou
ld make it obvious, which are the groups of notes (pdfs), for which keyword groups exist.
