Things I'd like to see, off the top of my sleep-deprived head:
Something to auto-summon a minion(specific or random) when you log in or res.
Recipe back-links to show the entries for intermediary synth mats.
And indicator in item tool-tips showing how many synths that item is used for.
Item tool-tips only appearing when the icon is hovered over, not the entire entry line in menus.
Automatic mainhand change when attempting to repair an item not repairable by your current class.
Crafting log tracker that alerts you in some way when an item you pick up is a material needed to complete an entry you haven't filled yet. Possibly just a special marker placed over the item icon.
