Only one problem is that there no frame names unification, i.e. if
you have two frames named 'default' this stuff will take first frame

Embedded frame looks like that(really old screenshot, but concept is
shown) - http://lgarc.narod.ru/xwem/xwem-frames.png.
Frame marked  at the right-bottom is embedded frame it is handled
as normal client in 's frame window.
To create embedded frame try `H-u H-x 5 5'

Actually yes, but there no really user interface for this, you can
install `xwem-frame-creation-hook' to change params, but I'm not sure
it will work.

Great! I did not know abouth this :)

Yes, i tried to keep XEmacses way of binding default keybindings, so
XEmacs users can start with xwem on intuitive manner. And there no
need to overload memory with new keybindings :)

For me registers are pretty usefull, I use them everyday when doing
editing in XEmacs, and quite often in xwem(esp H-x /), but not that
often as in XEmacs.

Yes, there no need to change it, but sometimes it is usefull add new
ones, for example xwem-special, xwem-rooter do it this way.

A little benefit. For example you run application with some
parameters, like 'xterm -fg orange -bg black' or just want another
intance of program which you run much time ago and dont remember how
you have run it.

It is a character, so pressing `H-x / p' or `H-x / H-p' will not
differ, because only 'p' character considered.

Great! How do you think when it will be possible to start with xwem
for ordinary XEmacs users? :)
