Combine them (get them together)
 

As a result of a search you simetimes get the same file more than once with slightely different names but the same size.

It would be nice if you could download these ''different'' files (with the same size) to one file. In this way you would heave more sources for the same file.

Xolox has started using SHA1 hashes, the primary method of doing this. (same file, different name)

What do you mean with ''Xolox has started using SHA1 hashes''?

- Xolox is busy developing this feature?, or
- Xolox already has it?

In case of the latter I'd like to know how to use it

It is automatic and available in the latest beta. Note: many files that may appear to be the same really are not similare enough to have the same hash.
