If you are taking requests I'd also like:

1) The file selection dialog to be resizable (at least vertically).

2) The text widget to accept clicks in the middle of the text and move the
insertion bar there rather than to the end of the text.

3) Support for 16 bit PPMs.

4) Dithering support in 16 and 24 bpp mode.

Amen to (2); that's the one that drives me the most crazy. 16-bit PPM support (3) is as trivial as compiling PBMPLUS/NetPBM that way (although you'll still be limited to the internal 8-bps depth). Dithering support (4) already exists; look for Guido Volbeding's (I think) fixpix patch.

P.S. One of my favorite features: [pbm junk] | xv - (the command line rocks, too!). And the fact that it uses its own widget set means you don't have the dependency hell that so often accompanies GTK+, Qt/KDE, etc. Maybe I'm the only one who likes to drag along the same binary from distro to distro without constantly recompiling the damned thing...

16 bit PPMs

If you use current Netpbm this is not a compilation option; it always handles both 8 bit and 16 bit PPMs.

But I suspect xv doesn't use the Pbmplus/Netpbm libraries. Most programs don't -- they just interpret the PPM format (or, usually, some subset of the PPM format) with private code.
