PC app to download a list of files over HTTP

I would like a piece of software built for a PC/windows 10 environment based on the layout and actions of FileZilla that instead of downloading over FTP, it will be over HTTP. It will begin a download files by either a) parsing a user supplied text file list of URLs (direct to files, see attachments), or b) parsing an HTTP open directory given a single URL and create a list of links to files (ex. [login to view URL]). When I say "parse", I'd like the list of files to be displayed in a file tree with parents and children nodes, just as FileZilla would do with an FTP site. After the list or website is parsed in the left panel, I can select files where to download the files over HTTP on the right panel and put them in a download queue. The downloading will need good error handling as requests will time out or be disconnected. Resume capabilities of the queue is a must. If download resume is not allowed then the software will start that file download over. Allow the user to set the number of download threads. If the chosen number of threads is more than the website will allow, then the software will automatically back off of the user input and go with what is working. The user will also have the option to recursively save the files as they are in folders on the website. Essentially, this is mirrored after how FileZilla operates. Finally, I'd like the software to be able to bookmark base URLs for future visits and run a simple ping operation on the saved URLs and display whether or not they are active. The bookmarks will be displayed as a table showing the URL, last pinged date, and current status ("Active"/green, "Down"/red)
