Change it so that the checklist automatically refreshes. Having to click the refresh button every time a change is made is a pain. Being able to do this with a key stroke, ctrl-s in Needles, is much easier.
When the checklist is refreshed, have it return to the item you were on before it refreshed. The way it’s set up it goes back to the top of the checklist after refreshing, then you have to scroll back down to where you were working. Inefficient.
Eliminate the parent/child notification on the checklist, unnecessary, too much clicking, also visually redundant.
Allow for customization of the checklist codes text color. This helps to visually locate items more quickly.
