answering the last question:
on the Menu: Preferences: Get Plugins: <choose> (restart will probably be required, but you can install many before doing that ONCE after the last one)
Any space BETWEEN fields is controlled by the
send to ... template
{title}-{Authors} just a dash, no spaces
{title} - {Authors} with gaps
The comma within the {authors} field is the Ln, Fn standard
Filenames are trimmed to be compatible with all OS pathname limits
