This extension adds features to improve your download experience on PMVHaven.com. The features include:

An instant-download button that when clicked will download the chosen video in the highest quality available.
Choose your preferred download source (CDN or HLS). When using HLS, specify your exact preferred resolution (from 360p up to 4K) or leave it on Auto to reliably fetch the highest available quality.
Auto detection and smart fallbacks if a video is a CDN .mp4 or .mov, or requires HLS stream processing.
Customizable video filenames. Add the creator or uploader, video quality, and upload year before or after the video title, customize the divider, or simply use the filename given by the website.
Automatically sort your bulk downloaded videos into their respective creator or uploader folders by checking a box that remembers your preference for next time.
A button on video cards to quickly open up the .mp4 URL in a new tab.
Checkboxes to select and bulk download up to 500 videos at a time into a lightning-fast floating download queue.
Native file sizes displayed directly inside the download queue for each individual video, alongside a live combined total file size for your entire queue (e.g., "4.82 GB").
Seamless syncing. Selected videos are saved in the extension's local storage and sync instantly across all open tabs.
True background downloading. Your download queue runs entirely in the background, meaning it will keep processing and downloading even if you safely close the website tab.
The ability to pause an active download queue to easily add more videos mid-session.
A live session tracker inside the download queue that smoothly tracks your total session count (e.g., "28 of 82 downloading...").
Live visual progress bars directly inside the download queue for every active video.
Smart duplicate detection that automatically recognizes different URLs pointing to the exact same video and merges them so you never accidentally download duplicates.
Smart zero-request data sniffing and local caching that passively reads video details and file sizes directly from the website's own traffic, guaranteeing instant loading without ever triggering rate limits.
Click a video inside the floating download queue to open it in a new tab. Fully supports Left-click, Middle-click, and Ctrl + Right-click natively.
Customize the height of the download queue by selecting how many videos are visible at once (between 3 and 12 items), complete with a sleek custom scrollbar.
A button to clear all videos from the download queue (with a safety confirmation prompt), accessible from both the website and the extension popup.
A "Select All" button on both profile pages and playlist pages to more easily bulk download all videos from a creator or collection.
A robust, tabbed extension popup menu to quickly view your live queue progress, configure settings, and pause, resume, or clear downloads without needing to be on the website.
A pin button in the extension popup that turns it into a persistent, always-on-top window that won't disappear when you click out of focus.
Settings to adjust your concurrent downloads limit to control network usage (from 1 up to 20 videos at a time).
Change the videos per page value all the way up to 9999 videos (website default max value is 48).
