I've posted an update to Boss 1.0.
If you use the "Combine Files" feature, you may notice an improvement in speed, as it is now about ten times faster than before, but unless you have combined files with many thousands of verses in them, like twenty thousand verses or more, you will likely never notice any difference at all.
I plan to get to Boss 2.0 sometime, hopefully sooner than later, in which you will have the option to view the WLM files in native BW format as well as the current format, and also hopefully I'll have a few other additions and improvements as well.
I'll post a message here whenever I get that completed.
