Like in soundhound but than with the songtext and guitartabs

This would allow a set list to be created that would have each song containing a reference pitch and backing track that could be played wirelessly and hands-free (sync'd between multiple iPads for other band members). IMO, the ideal BlueBoard bank would look like: Next Page, Previous Page, Play Pitch, Start/Stop Song.

Currently, the metronome only works in increments of 4, which can be a bit confusing when working with a song in a different time signature.

When a Set List contains several songs, it is difficult to find a title quickly. Applying colors to the song names would help notice them (every color could mean a category, such as style, tempo or genre)

A Teleprompter function for lyrics, the ability to set the speed for the scroll or stream to match the tempo of the song being preformed.
Currently the lyrics appear on a page, and even with a large font are difficult to read unless your attention is centered on unreal book.
With a Teleprompter function you would have the ability to have the iPad at waist level and read the lyrics as they scroll by

The connection ok/disconnect message is very small. Could there be an option to make it large (perhaps in Settings>Network? so those who need to see can easily see it).
Also the Master might need to check all slaves are connected, so a list of the connected iPads would be useful.

I have a lot of metadata associated with PDF files I originally prepared for MusicReader, and I don't want to have to key it all in again - I have a couple of thousand songs. I could extract the information from MusicReader's library.xml file, and put it into a spreadsheet with a little programming effort. There would have to be separate methods for single-song and multiple-song (indexed) PDFs.

if the slave has the toolbar showing, when the next page loads from the Master, should the toolbar disappear (at least after a few seconds)?

When the Master loads a PDF from song index and it is missing from the Slave, only the Slave gets a message but the Master has no message. It should.

with a PDF using the TOC option to find the songs, it will easily crash. Sometimes this is done by tapping out of the TOC area, other times tapping back to the song index, sometimes re-entering TOC for that same PDF from song index.

For example - when using a multi-page chart, the first page view setting often means subsequent pages have the top or bottom cut-off. If one sets subsequent pages to be as large as possible without loss, then the first page is too small - if you get the idea....

Did you already think about implementing a way to quickly pop up how a specific guitar chord is to be played? Especially for chords like EmSus6 and so on. Would this fit into the general goal of unrealBook?

Could you add a duration (min and sec) field to each song and to the set list creator / editor so that when you build a set list, you can calculate just how long the set will be? Would also be nice to be able to add a factor for time between songs so that's added to the overall set list time. Would also want to add in breaks and a time for each. Would also be nice to enter when the time of day the set starts so you know exactly when you'll be taking a break(s).
