Handbook suggestion: Remove references to previous MS versions
The current Handbook is cluttered with references to previous MuseScore versions. Why? As a technical writer, this strikes me as completely unnecessary. It makes the Handbook much harder to use. (Several times I've found a command in the Handbook, then wondered why it didn't work—because I'd failed to notice the Handbook was referring to a previous version.)
If users had to pay for MS upgrades, it would be different. But MuseScore is free. So rather than feeling obligated to keep documenting previous versions, I suggest you begin each Handbook with something like this:
NOTE: This Handbook applies to MuseScore ver. 1.0. If you're using an older version of MuseScore, please visit www.musescore.org and download the current version to take advantage of the improved commands and features described here.
