Ever since the introduction of the option to pause certain types of files and declaring them "unimportant" for the unrar process, i love using this feature.
However if a collection is incomplete these files are usually included in the parset and therefore need to be repaired aswell. Especially in small repairs this can double or tripple the amount of par blocks needed and prolongs the repair process.
Thats why i would like to see a pre-repair routine where alt.binz checks wether files marked as missing in the parset are actually paused in the queue and unpauses them before calculating and downloading repair blocks.
