I have to handle large files for numerous restaurants

As I got a new automotive client recently I have to keep track at all these projects. (100+)

So I need to have all necessary & connected documents organized.

I miss the following n Nozbe:

• Can I only “hotlink” files? – meaning accessing them from their original server location without saving a copy upto Nozbe?

• If not – why do I have to purchase an multi-user account just to get more storage?

Is there no option to expand storage with a single-user account?
• is there an option, to somehow rightclick e-mails in Firefox and directly assign (and include) them to specific projects in Nozbe?

Also I have one technical question:

• Why do I see only starred actions in my calendar, though the time-field says it´s got to be done today?

Thank you
