So you go against consistency to follow the HIG, then immediately stop
following the HIG?

Good.

I guess that's ok since Redraw is just a failsafe for imperfect
rendering.

Fair enough.

Seems to match what many other programs do.  Plural is only for menus
like Tools where the plural refers to the items in the menu, not to
things being operated on by the menu functions.  Please make sure that
all relevant files are updated.

That is probably good.

Nifty, aren't they?

The menu bar is getting awfully wide already.  Though it could go under
Diagram.  Or are you suggesting a context menu in the Layers dialog?

Do what I do, look at what's there and figure it out.  You'll need to
add a menu item in app/menus.c, initialize those that can be ghosted in
menus_initialize_updatable_items (adding appropriate struct entries in
app/menus.h), add sensitivity updates in app/diagram.c, and add callback
functions in app/commands.c.

To keep the menu managable, I'd suggest having a Visible submenu for
changing which layers are visible, and similarly a Connectable submenu.

Not exactly the same as grouping/ungrouping, as there is no object in
the diagram involved.  Should make it easier, but you'd still have to
add the undo objects for it.

You'll notice that I have reserved Alt keybindings for the tools.  I'd
like to keep it that way.
