File Size column possible?

[jacoghi]

1st of all, amazing work. Completely switched from both lithium and tinfoil after trying this one out.

Now, not really an issue per say, but more of a "feature request" as long as it's feasible and doesn't clutter the whole thing up.
Would it be possible to add a file size column so one can know whether there's enough free space available before installing?

Thanks again for this, really appreciate it.
