Suggestion: Option to download heads..or files.
 

Put an option to be able to enable or disable downloading of heads..or other certain files.

Add like a button..or selection..and make like a text field..where you can specifiy the head you want to see..the only head.

I just deleted 5000heads out of my heads folder..and my graal runs faster..

Can cause a problem if servers have custom gani systems, and are using the 'HEAD' attribute of a gani (.headimg).

Also, I am not sure that deleting heads would make Graal run faster. It might make Graal load faster though.

Do you have the filename cache turned on (press F3, General tab, make sure it is unchecked)? If it is turned off it will take longer for Graal to start.
