3ds Max :: Ribbon And UI Customization

I'm currently switching from my "old" customized UI with a few dozen of my own macro scripts and toolbars and would like to get all of that to the ribbon, but I encountered a few obstacles.

1. Is there a way to use the old bitmap strip icons for a given command, the way you can change the display options in a custom toolbar or .ico files are the only option in a ribbon?

2. I'm trying to recreate the main toolbar (the default one in Max) in the ribbon. There are two problems with this:
- first I don't know how to recreate the dropdown lists (like named selection sets, or render presets).
- second thing is that when I use a command in the ribbon that has a certain icon assigned to it ('select and move' for example has the crossed arrows and you can see them in the customize dropdown list with commands) it works fine only for the small icons. The field for the large icon is empty and the small icon is visible in the ribbon property dialog, but there is no path for the icon image, so it apparently works with the .bmp file. Go figure. Would be great if Max would automatically assign that icon to both small and large icon field.

3. I would like to be able to show/hide the menu, command panel and if I won't be able to recreate some of the features in the main toolbar, hide it as well. The most efficient way for me would be to have it available under a key shortcut or quad menu, but for some reason the command found under 'customize user interface' named show/hide menu doesn't work at all. Show/hide main toolbar toggle, which is a separate command for some reason does work. Of course there is an icon in the quick access toolbar that actually works, but it's two clicks instead of one key and with the tiny icons it's not that fast.

4. Is there a way to make the ribbon tabs show up on the right side of the ribbon in the horizontal position or move them freely, centered ... any other configuration ?

5. Is there an option to merge from a .ribbon file only certain tabs from a ribbon and not the whole ribbon ?

6. When you hide all toolbars the only way to get them back via the right-click menu with the list of toolbars is to click on the very thin (few pixels wide) strip on the right side of the command panel. Not a problem if you know where to look for, but it's really hard to find. Luckily I have a key shortcut for the main toolbar, but I can imagine that a new user might freak out a little bit.

7. Finally it's more of a suggestion, than some problem, but it would be great to be able to take any toolbar and with one click convert it to a ribbon tab.
