Just look into Feature Requests and Ideas section of the forum. There are always some area to improve.

I don't see too many things that would warrant a release of a 'new' version - most requests are just changes or enhancements to existing features. I really question the practicality of some ideas.  

For example, the ability to control a number of tablets from a single master unit (as mentioned by Mike).  This might work for single page charts, but I can foresee all sorts of problem with multi-page charts, where different players will want to change pages at different places.  Maybe the best option here would be to call up a specific chart by means of the master controller, but leave the page changing up to the individual users.

As Mike well knows, I am always a little concerned about feature creep in software which, if uncontrolled, can easily turn a great bit of software into an unusable piece of junk.  MSP is a great bit of software and I'd like to see it remain so.
