 Here are some ideas under discussion for the next major revision of
 the SANE API:
@@ -16,3 +16,26 @@ the SANE API:
  o Support for other multimedia types, such as audio.  This probably
    would also require adding a write() interface to the SANE API.
    [Suggested by Erik Troan <ewt@redhat.com>.]
+
+ o add support for buttons etc. on the scanner/camera
+
+ o add support for sending messages from the backend to the frontend
+   (e.g. for warm up time)
+
+ o Change of the version number system (the current standard version
+   system is not really used in the SANE distribution).
+
+ o add more frame types
+
+ o add alpha channel so that RGBI scanners like Nikon LS-20 can
+   send infra-red info back to gimp for post-processing
+
+ o Might be nice if arbitrarily defined multiple channels, were possible.
+   Some way of indicating the number of channels possible, and some
+   details (wavelength, bandwidth, ...)
+
+ o Don't call any other SANE function if sane_init() fails
+   (status != SANE_STATUS_GOOD)
