Please add a new feature to the "Download Files" action - new setting "Download Limit (Kb)" (I think that kilobytes are more convenient than bytes). If you specify a value for this option, the action will only download this size from the specified file, while returning successful execution.
This is necessary when you need to download only a small amount from a large file. What speeds up the script, especially in multithreaded mode with bad proxies.
You could also add a similar setting to the "Set Download Location" action and rename it to "Set Download Options".
And it would be cool if you added the Result option, as in the "Page Load Wait" command:
