I removed (as a try) the space between the leading | and the first chord Gm7 and got an error message! After clicking on the offered message "Would you like to fix those errors" nothing got fixed! Does that intentionally mean BiaB will automatically fix some easy typos or is it just a memo to correct the phrase (than this second message is not needed, as there already was an error message)? Also: I could just find this somewhat confusing line in the mentioned log file:
Error in chord  úšw ` € 21`: €Ñ, at bar 1
Instead of referring to the log file BiaB should highlight the the incorrect part of the input (and even better: make a proposal for a correction).
