personally I use this one 1DM+. and this one I tried it before FDM

the benefits is using refresh link to continue download failed file (time reach, internet connection), download torrent file, limit speed connection, etc.

in nightly previous version before (around 2-3 month ago) it always show download manager in available app but in lastest nightly it only show browser of download manager. (I'm not coding so sorry if I mistaken but it has 2 activities when opening urls, open via browser and run downloader. (see screenshot)

this screenshot taken in LinkSheet app that showing only 1dm browser

this screenshot taken in android sharing popup that also showing 1dm downloader.
