Feature Proposal: PDF enhancements, Secure Wipe, Quick Delete, In-App Browser

Subject: Feature Proposal: PDF enhancements, Secure Wipe, Quick Delete, In-App Browser

Hi Tella Team,

I love the app and would like to contribute code for four specific features. Before I start, I want to check if these align with your roadmap and ask a few questions.

Proposed Features:

1. Enhanced PDF Reader: Add state persistence (remember last read page), Go to page input, Text-to-Speech (TTS) read-aloud, text highlighting, and sticky notes.
2. Secure Wipe on Import: Prompt the user to Secure Wipe (overwrite data so it is forensically unrecoverable) the original file after importing, instead of just standard deletion.
3. Quick Delete Security: Add a dedicated secret PIN to trigger Quick Delete, plus a configurable setting to auto-trigger it if the wrong password is entered X times in Y minutes (brute-force protection).
4. In-App Browser: Add a built-in browser so users can browse and download directly into the app, preventing external browser traces (cache and history) from leaking outside Tella's secure environment.

My Questions:

1. Philosophy: Do any of these features conflict with Tella's core idea or security model?
2. Code Structure: Do you prefer new features kept in separate, modular files, or integrated directly into existing files?
3. Merge Criteria: If I ensure the code is perfectly optimized, cleanly organized, maintainable, and clean, will you accept and merge the Merge Request?

Let me know if I should open individual GitLab issues for these first. Thanks for your great work!

Best regards,

Start by reviewing the four proposals in the issue body and the project's security model; no source files, tests, or entry points are identified. Clarify roadmap fit and security requirements with the maintainers, then split the proposals into separate issues with defined acceptance criteria before implementation.
