Mr. Liberzon,
I am just spending some of my free time with Spider©. I find your demo (which has only activity limitation) very good and manual in English is quite detailed. I have a humble suggestion; if you can prepare a basic tutorial pdf , it would be very great for new starters to study software and people will not afraid from spending a quite time to a new software. Something like creating a project, create&assign codes, relations and resources, scheduling, etc. etc. as tutorials will be great if you can supply with demo. It will also help advertising.
Regards,
Safak
