Feature request: Custom fields, import anki model, picture import

Wow guys! This is amazing work! Can't wait to the new app version. Please consider the following features to make pdf2anki even better:

1. Define additional fields: My anki cards follow the 20 golden rules, however, i tend to forget things, even if it is concise and clear. therefore i've defined several additional fields in my decks to help me remember or providing additional data, e.g. an explanation field or a source field: let's consider studying neurology and i've been asked about symptoms for sequard brown syndrome. then i might encounter that i don't know the syndrome anymore, therefore a quick reminder in my explanation field, with a link to a book or a website i got this info from is helpful (or i just need to see the fact in context again [like from the textbook]). it would be very helpful imho, if something like this could be additionally defined in your app as well.

2. even better would be to let an anki model be imported. let's consider that i have a french text, and only adjectives shall be extracted (not yet possible i believe?). my anki model for studying language consists of several additional fields to generate diverse cards from like antonym, synonym or example sentences. it might be tedious to define extra fields like that. if the model (structure) could be imported and the AI instructed what those fields mean, than that would made it even more easy.

3. and last but not least, that would be really the icing on the cake, consider picture support. especially for those concepts where it is vital to have an image to learn from such as anatomy, music, art, archeology, etc. it would be sooooo benefical to have a picture imported from the text as well. luckily most academic texts or textbooks refer in their body text to those pictures (e.g. see fig. 7 or alike). If a flashcard from this part of the text is generated, might it be possible to extract this image and add it to the prior defined field?

I hope my feature requests are understandable, otherwise let me know, so that i can clarify. Thank you for considering my ideas and i'm grateful already of how far you come! I hope this app can thrive and be around for long! My (financial) support included.
