Bread additives

Since I'm starting my 3-month bread machine odyssey, any suggestions for things to try out would be welcome.

Cooking with whole grain flours in a bread machine often leads to bread that is a little heavy for sandwiches, so I'm going to try adding some vital wheat gluten. No one in the house is allergic to wheat, though we try to limit our intake because its in everything, so a couple tablespoons per loaf isn't going to hurt anything.

I've switched to using mostly honey or molasses for sweetner in my breads, and I really like the results. I think I'd like to try malted barley to provide the enzymes to produce sugars for the yeast from the flour.

Any recommendations on using these ingredients? Any other suggestions that I should try for making interesting, healthy loaves in a bread machine?
