Just make sure it's a choice, and hopefully not the default. I've found
single-instance to be a pain in the posterior in most situations, especially
if you use lots of desktops.
Note that even a single instance LyX would support multiple windows, via
File>New Window.
Personally I'd much prefer if LyX could be configured for
single-instance use; this is where tabs are useful. At the moment
opening additional files can be a pain since you cannot simply use
your file manager for that.
If you're on Linux (or perhaps other *nices?), this is fairly easy to
do. I'm attaching a simple script that looks for a running instance of
LyX and tries to open the file there via the lyxpipe. If you set up for
your file manager to call this script for .lyx files, then you have the
best of both worlds. You can always launch a separate instance in the
usual way.
Obviously, you will need to adjust some of the settings for your own use
(and you may want to remove the kdialog bit). Better would be to make it
more general purpose. E.g., we'd need to parse the command line for
LyX's own options; use them if we find them; find the location of the
lyxpipe by grepping $USERDIR/preferences; etc. Then we could even
distribute it with LyX.
