Hi, Colm-

Those are useful suggestions. Some of them are, in fact, already in the pipeline. Please see the helpdocs here, where some of the things that will be coming are listed, too:

Regressors will be labelled, yep, as will the task name. Basically, we just need to put in the functionality to build the dictionaries to pass those along.

In terms of EPI-anat alignment, at the moment, I think that will likely stay in its current form, when using a reference template (and esp. with -volreg_tlrc_warp). The raw EPI (-> volreg base dset) and anat volumes will be shown in their own native/orig spaces, though.
