One of my friends saw that there is a boomark tool inside MSP and used it like so: Import a multi tune pdf as a pdf (ie without bookmarks), then set individual bookmarks via the bookmark tool. You can see those bookmarks alright, but they will never show up in the tune data base.

Hi RAc,
I'm a bit late to this party, sorry.
With the greatest of respect to your friend, I think they are trying to use the wrong feature.  Or perhaps it should be considered trying to solve the wrong problem.

As the desired goal is to be able to access individual pages/songs within a larger, multi song PDF then they should use a database entry per song which points to the correct page within the PDF.  Importing via bookmarks does exactly this.

Hi lawrie,

thank you very much for the detailed explanations. They are very helpful, but my point is that those should be in the docs or at the very least added to it in some form.

However, if you happen to have a pdf that already has bookmarks to locate individual tunes, you can use those to locate the tunes out of the box, yet you need to a) know or ensure that the pdf already has predefined bookmarks AND b) import the file via the "import pdf bookmarks" dialog, not the regular (and thus not bulk import) dialog.

That was our confusion, and I believe that adding a clarification to the docs would significantly help newcomers in overcoming the hurdle of trying to deal with multiple tune pdfs. I do not have any problem with the way it is implemented and do not request any software change, I just think that the documentation could be enhanced.

I think you've made my point here.  Easy to see if there's bookmarks in a PDF, just open it in a PDF reader, like Acrobat Reader...  If they're there and suitable then Bob's your uncle, and if they're not then don't waste your time buggerising around with the inbuilt bookmark function, just import the PDF using a CSV file.
That way they appear in the songs database and you don't need to mess around with the bookmarks tab.
