I've always felt something like this was missing from GTK+. I think I 
remember seeing a cool widget for this in Qt the last time I poked 
around in their RAD tool (I don't know Qt at all).

Along with this, it would be great to have YUV-ish support in Cairo that 
could somehow avoid or minimize converting a whole frame between 
colorspaces (ex. YUV to RGB) and make use of hardware YUV support. I'm 
not sure if that even makes sense, since probably lots of code depends 
on working in another colorspace, but it would make real-time video 
easier to get right (ie. not slow).

What about a more general GtkVideoCanvas widget that can help out here 
and maybe have a separate sink plugin in GStreamer that can pull frames 
from a pipeline and render to the canvas. Then it's not restricted to 
just being useful for Gstreamer apps but can be if using Gstreamer. 
Applications could choose to just use V4L2, DShow or libav* directly and 
render onto the canvas, for example. Each new frame could cause an 
expose/draw signal giving the chance to do OSD on it with Cairo.


Here's a couple more ideas:

SIMPLE TREE and LIST
It would be great to have simple GtkTree and GtkList widget sitting 
ontop of the extremely powerful GtkTreeView API for those many cases 
where you just need a basic tree or list box. The new widgets would not 
require a book[1] to explain how to use it. I saw a GtkTree in the API 
docs but it's deprecated, presumably because it doesn't sit ontop of the 
better tree view API.

TAB BUTTONS
I think Tristan alluded to this in another thread, but there is a common 
need for a compact button that can fit into small places such as a 
notebook tab. It's feels really dirty doing it yourself. This could be 
used in the next one...

NOTEBOOK IMPROVEMENTS
See Firefox.


I think that's it.

Cheers,
