Hi Nigel,

Your original Y register display code made it a lot easier for me to get started, especially as I wasn't at all familiar with the WP 34S codebase. The new Y register display code is already in the SVN and I've just committed the universal dispatch function patch. I'll commit the patch for the faster data entry once I'm a bit more confident it's doing the right thing.

Here's my take on the configurability of the Y register display in order of preference:
1  - Have it statically enabled (I see absolutely no downside and it saves firmware space).
2a - Configure it through the mode menu and the currently unused bit in _ustate. Since it's a purely UI feature and has no effect on calculations, it could make sense to use an internal flag.
2b - Configure it through the mode menu and the Y flag. The advantage compared to 2a would be that it'd be very quick to turn it on or off.
3  - Configure it through the Y flag only.
If it's configurable, then Y register display should be enabled by default because it'd be much easier for (some) advanced users who know exactly what they want to disable it than it'd be for beginners to discover the feature.
