Sorry if this has been requested before, but I wasn't able to find it when I searched. It seems that making a button to enable/disable multi-source would be useful for times when you find a file which is perhaps shared by one person who happens to take a while to reconnect to while getting numerous segments. Therefore, upon finding this file, you could quickly turn off segmented downloading and then turn it back on after you have the file. This can already be done by just going to settings I know, but I think it might be a useful toolbar button for those of us who tend to use this feature often (I change it back and forth maybe 5 or 6 times a day). Thanks:P
Edit: Sorry for the title, I meant toolbar.
