Display Customization — dark mode, font size, accents, hyperlinks

Hello Flashka Team,

I am enjoying the app, but I have three specific suggestions to improve the experience, especially for power users:

1. Dark Mode: Please introduce a native Dark Mode. This is essential not just for customization, but to reduce eye strain during long study sessions.

2. AI Editing in Study Mode: It would be highly efficient to modify cards with AI directly while in 'Study Mode.' Navigating back to the main deck list to edit a single card breaks the flow.

3. Chronological Card Insertion: When I manually add a flashcard from a PDF (because the AI missed a concept), the card should be inserted chronologically within that specific topic or section, rather than appearing at the very end of the deck. This is particularly vital for students who study from very large files, as it ensures the logical flow of information is maintained.

Thank you for listening to user feedback!
