I would find that allowing for fractional response variables in mixed models would be extremely useful.

Best,

Nick Cox queried about #6, as to why I didn't just use a -if- qualifier. -if- works if I'm only plotting a scatter graph. If it's a line graph or area graph where I want to clip (or crop) some of the plot region, that cannot be easily done. I note that in the meta-analysis program -metan-, the authors have already anticipated this kind of cropping for forest plots, in that if one of the studies has huge confidence intervals, -metan- will not change the scale of the plot just to accommodate that one study, but instead draws arrows for that particular "tree" to indicate that its width exceeds the indicated range of the axis. If I have the time, I can probably write a wrapper program for -twoway- that does that more generally.

If we could export some graphics (in particular I'm thinking of SEM graphics) to any one of several graphics packages in LaTeX it would surely make for much nicer looking output and provide additional capacity for end users to further customize things on a lower level.  Given how many Stata users also seem to be users of (La)TeX, this could also provide more users with greater flexibility when it comes to adding specialized text to graphics and/or generating more complex output that may or may not be currently or easily supported by user-written commands.

And although they typically don't comment on things under development until the next release, it would be really great if some of the StataCorp folks could comment on the feasibility of implementing some of these things within a single development cycle (e.g., it wouldn't be possible/practical to do X because it would require redesigning the entire graphics engine while still maintaining backwards compatibility with old graph files, but could be accomplished as a longer term goal).  There are probably lots of things that users would like, but many of us probably don't appreciate the true magnitude of our requests and hearing back from the StataCorp folks could probably make it easier for users to understand that and try to figure out ways to work around the current limitations.
