Re: designing the galley
If the rails project off the cabinet face they needn't interfere with countertop area...
One thing that really helps with counter clean up, with fiddles, is to have an under-hung galley sink.. We converted a conventional drop in sink to underhung.. simply drilled the flange and attached it to the underside, then trimmed the hole edge. You can then cleanly wipe everything over the lip of the sink cutout.
