I need a PDF editor to create internal hyperlinks in a document. I purchased a huge PDF and would like to be able to link internally to keep me from having to scroll or search the relevant data when needed. This thing is massive, over 1100 pages, and it's for ttrpg so there are a lot of tables, locations, special items, etc. that I'd like to be able to link to and find quickly.
I'm okay with paying for software if it will include this feature specifically, however, I don't prefer the subscription-based services I keep seeing listed in general searches. Bonus points: no major hassle with licenses when upgrading my OS to the newest LTS, and I can also run it as a Linux app on my Chromebook.
I've installed that on my desktop, but I haven't really tried it out yet. I've also been reading up on Sigil as well. Considering converting it to an epub to read on my phone and e-reader while out and about.
Scribus is certainly powerful. You can also use python scripting to automate edits, so maybe you could even use regular expressions in a script to automatically insert hyperlinks.
