Is there a universal boot manager for Linux?

Question

linux

In connection with the decision to replace XPEnology, on the home server with OpenMediaVault, the question arose of organizing downloads and torrents.
DSM has a universal DownloadStation. It understands http\ftp downloads as a normal download manager, supports several file sharing network protocols (eg bit-torrent, eMule, NZB and Xuelei-Lixian). He is also able to download files from file-sharing networks and YouTube (for example, 4Shared, Mega, DepositFiles, etc.), and he himself receives a direct download link, and when the connection is broken, he resumes it on his own.
Under classic Linux, there are programs that can do all this, but each has its own piece:
1) WGet, Kget, etc.
2) Transmission, rTorrent, Flush
3) JDownloader
The main advantage of DownloadStation is its versatility. Just feed him the link and he will do everything he needs. Ease of use tested on parents.
Is there anything equally omnivorous in classic Linux? Preferably with a web interface.

Answer 1

Nobody bothers to make a watcher for the directory, which will parse what came to it and send it for download

Answer 2

Found an interesting variant of PyLoad : torrent, http\ftp, .
file hosting; written in python.
But the interface is not particularly friendly, unfortunately, can not be called.
