Chrome OS, you can install the popular open-source download manager, uGet.
Yes, it works pretty well using the Linux Container and I did not face any issues on my Chromebook. I was able to download a video from YouTube by just pasting the link and uGet took care of everything.
Open the Terminal and execute the below command.
sudo apt-get install uget
After the installation, you will find the app in the app drawer inside the Linux apps folder.

Open Terminal and execute the below command.
sudo apt-get install inkscape
edit a bulk of images in one go. If you ever wanted to use an app like Microsoft Paint on Chrome OS, this is the best option and I think, it’s much better.
