4chan Reddit-like frontend

4chan replies can quote **several** posts at once, so a strict tree doesn't fit. This extension uses **full duplication**: a post is shown under *every* in-thread post it quotes (including OP). - The **first** copy of a post renders fully expanded. - Any **duplicate** copy renders collapsed with a `duplicate ↑` badge; click the badge to jump to the first copy, or click the collapsed comment to expand it in place (children build lazily, so big threads stay responsive). - A post that quotes nobody (or only dead / cross-thread posts) is treated as a top-level reply to the thread and placed under OP. - Greentext, spoilers, and country flags are reused straight from 4chan's own rendering. The view uses a dark theme (olive page / brown cards) so greentext reads clearly. - **Nesting is color-coded by depth** (RES-style): each indent level's thread line gets its own color so a single conversation is easy to follow. - **Poster handles** — on `/pol/`-style boards every poster has a unique ID. If they kept the default "Anonymous" name, it's replaced with a stable, readable handle derived from that ID (e.g. `WiredLoon07`), colored by the ID's own color, so the same poster is easy to track. Posters with a real name are left as-is. - **Redundant `>>NNN` references are pruned** from both the comment text and the meta line's backlink list — the nesting already shows replies. Only *same-thread* quotes are removed; *cross-thread* quotes (`>>N →`) and *dead* links (deleted posts) are kept, since the tree can't represent those. - **Inline media** — click an image or `.webm`/`.mp4` thumbnail to expand it in place. Both images and videos resize by **dragging anywhere on them** (aspect preserved); for videos the bottom control bar stays usable and a plain click toggles play/pause. A plain click on an image collapses it again (or use the ✕). Videos pause automatically when scrolled out of view. Image previews load the full image (lazily) for a crisp "at a glance" thumbnail. - **Default video volume** — webms/mp4s start at a chosen level (default 50%) instead of full blast. Set it from the toolbar's 🔊 slider or the popup (the two stay in sync), and any level you pick on a video becomes the new default automatically. - **Gallery** — the toolbar's **🖼 Gallery** button opens a full-screen viewer over all media in the thread. Scroll, arrow keys, or the ‹ › buttons move one post at a time; a filter button cycles **All media → Images only → Videos only**; the original file name is shown under the counter; Esc or a backdrop click closes it. - **Custom theme colors** — the popup has color pickers for the page **Background** and the **Posts** (comment box) color, with a **Reset** to the defaults. They're stored per-browser so your palette isn't universal. - **Friendlier timestamps** — dates are reformatted to your locale and each comment shows a live "X ago" on the right, refreshed every 10 seconds. - A faint divider separates each top-level thread (direct replies to OP).
