feat: Save Downloaded Media With Account Username in Filename

[baselalhabib]

Before creating a feature request...

• I have read through the FAQ
• I have made sure this feature has not already been already suggested

Description

Currently, downloaded Instagram media is saved with generic filenames (e.g., IMG_1234.jpg), which makes it difficult to identify where the content came from. For users who save posts from multiple accounts, this results in a messy and unorganized media library.

Describe the solution you'd like

Implement a filename format that includes the Instagram account’s username when saving media. For example:
• @username_postID.jpg
• @username_2025-09-05_1530.mp4

This could be:
• Enabled by default, or
• Added as a toggle in the tweak’s settings, allowing users to choose between default iOS filenames and account-based filenames.

Describe alternatives you've considered

Using external renaming scripts or iOS Shortcuts after downloading (not ideal, adds extra steps).

Good idea! The only reason I didn't add this originally was because of possible file naming conflicts, that would cause naming collisions between files. Do you think the best way to avoid this is to show a message saying you already have this file downloaded, or instead saving it under a different name (with something like a (1) at the end)

Thanks for considering this feature!

To avoid filename collisions while keeping things organized, a possible approach could be to include:

1.	Username — the account that posted the media.
2.	Media type — feed, reel, or story.
3.	Post date — formatted as YYYYMMDD.
4.	Unique media ID or shortcode (if available) — if Instagram provides a unique identifier for the post or individual media items, it could be appended to guarantee uniqueness.

Example filename:
@alex_feed_20250905_123456.mp4

•	@alex → account
•	feed → type of post
•	20250905 → date of posting
•	123456 → optional unique ID or shortcode (or last 6 digits of media ID)
