Search for words within the boards in "Manage grid" section
Add an option to search for words used (or not) within the boards and list the boards in which is being used. This is an option highly demanded by users.

What do you mean by "or not"? Do they want to search for a word and get a list of grid where this word is not used?!
It could be a filter option (we don't think about it) but mainly means that if the word is not used in any board, it doesn't offer results and the system advices that this word is not in any grid.
I've added a first version of search for elements, see https://github.com/asterics/AsTeRICS-Grid/discussions/239#discussioncomment-7693891 Please tell me if my solution also covers this issue or if this is something different (or how we could add features to my new implementation in order to also implement this issue).
Love it. Please also add the option to access the search when in fullscreen as discussed here https://github.com/asterics/AsTeRICS-Grid/discussions/239#discussioncomment-7729028 It would be also nice if the whole path was shown and highlighted visually, step by step. At the moment it jumps to the correct page and highlights the word there. If it instead would continuously highlight the buttons one has to press to get to the correct page and button, that would help for learning the path.
