The main workaround for the lack of a sig or logging functions in CheckVist is to make use of the colors feature. I assigned black, red, blue, and green to my first four workers so that they can self-identify (though only on a line-by-line basis, because color, unlike bold or italic, applies to the entire line...which makes it impossible, for instance, to signal one's edits of other team member's work). When more workers came into my project, I started assigning the outline colors, which was even more kludgey, because that styling dominates so much, visually. With more than 7 people, there is no way to self-identify. CheckVist could at least aid this workaround by enabling more colors (violet? orange? brown?) with the 7, 8, 9, and 0 keys. Preferably font colors, rather than outline. More effective, of course, would be to add tools to make collaboration truly feasible. But, meanwhile, this help with the workaround would be easy and appreciated.
