Set the maximum amount of downloading files #245
Description
Is your feature request related to a problem?
However many files are clicked to download, all start downloading without waiting queries.
At some low I/O performance storage, too many writing files cause abnormally slow total writing speed.
Moreover, because Telegram and network carriers limit users' downloading speed, it touches the limit with two of three downloading files.
Describe the solution you'd like
Thus, I request a setting that limits the amount of download files, with default value 2 or 3.
Describe alternatives you've considered
None
