Re: NWC2 enhancements
G'day Francesco. Welcome to the club 
- Multi-staff (vertical) selection : the possibility to select a set of staves at once. For example, I'd like to select a section of orchestral work in order to delete, move or copy it. Making it staff by staff is slow and error prone.
This would be very nice, but it is unavailable. Given how NWC works I suspect it is unlikely to eventuate. HOWEVER... If you explore the User Tools facility, there is a tool available from the Scripto (www.nwc-scriptorium.org) called "Cut/Copy and Paste Measures" (http://nwc-scriptorium.org/nwc2scripts.html) that can facilitate what you want. For more info on user tools check out some of the other links you'll find there.
- Better management of multiple void measures. When managing a single instrument score it should be beneficial to have a mean to include repetition numbers for multiple void measures. Using a simple text on top of a single pause measure obtains the visual effect, but the measure numbers, which are very useful when directing an orchestral work, get disaligned. It should be needed some "special" text which takes into account the repetition number and sum it to the measure number in order to avoid the disalignment.
Again, user tools... If you create the score as normal, including whole rests in bars to keep the numbering straight, then you can add a "multi measure" rest. Whilst it can be done manually, there is a user tool called "Multi Bar Rest" that makes life much easier. It requires that you install a font that supports the additional characters necessary.
These are:
- Boxmarks
- Boxmark2
- any of my *Dings fonts
Available from the Scripto: http://nwc-scriptorium.org/helpful.html
- Management of ' | % | ' measures in order to make repetitions of the same measure a number of times with reduced space should be very beneficial especially for wind band booklets where the space is limited.
This can be achieved in the printed version using characters from the fonts mentioned above and placed as text. Unfortunately for the playback to be right you still need to place the notes. They can be on a separate, hidden staff OR in the "real" staff but with visibility set to Print|Never. The second method looks untidy in the editor but will print fine.
- The current implementation of musical ornaments is limited to small notes (appoggiatura/acciaccatura), while it should be nice to have also things like trillo (mainly), mordente, gruppetto, and so on. I understand that there are a lot of ways to execute them, but maybe it should be possible to provide some default implementation, with the possibility for the user to customise it as needed, providing a personalised template. Using text plus hidden notes is possible today but it's slow and at the end of the day not practical for a real usage.
Concur, except that I think it is practical for real usage - I do it all the time...
- It seems that only triplets are managed. It should be useful to have also other numbers of group of notes managed : 2, 5, 6 (very frequent!) at least.
This is so. N-tuplets is a long standing wish. (NB sextuplets can be "fudged" by using triplets)
