I wounder if there is a way to get a transparant toolbar in any way?
Anyone know if its posible?

You can do it with Lucy, panels get treated like any other window so depending on the policy you will have to have other transparent windows.

The system described by Koan actually is the only one, since no transparency is provided by toolbar.
The other way is to play dirty....
Create your bar... =)
In the graphic setttings, choose no frame for the bar
Then as background, choose pattern.
Here starts dirty way: select pattern choosin a small ".mim" object: an "arrow_left.mim" for example (but you can draw a smaller one.. should be better..). In this way, only the mim will be displayed and the rest of the bar will be completely transparent.
Why a .mim object? I tried with a real png with alpha, but no transparency effect at all...
When you will put icon in the bar, that .mim object will stay behind the icon image, invisible. Obviously, if the icon image is a transparent png the effect could be ugly... =(
Next step is to set MUI Ambient: go in the "Button" section" and select "Pressed". Then set the effect on "Same as parent object" with 0% value. This avoids to draw coloured bokes in the bar when you select a program icon, making it only blinking.
And that's the effect:

The three icons above the bar are in a.... transparent (fake) toolbar!
Problems: you cannot open or close that bar. Fake transparency effect will become a real garbage effect.
The same if you move the bar...
So if you decide to add a button you will see the bar loose its transparency. Adjust position, fix your bar and after the reboot all return as it was before.
This method is usable even with Polynet bar provided that buttons have no effect when pressed to avoid blurring effects (if "tint icon" selected... Not tried the others.... ehm..)
.....waiting for a real or faked transparent bar...... with personal MUI settings

Why not using icons left out in ambient's screen? That "Leave out" function, a heritage from Workbench 2.0, is still there. It's available in the context menu of any icon.

...ehm...
You are right! That's the finest way to do it, as to use Lucy.
Remembering that you can set the "leave out" icons without the shortcut arrow and put them in a row simulating they are in a bar (or creating an opportune background)
Just to play a little with MorphOS....

You can't drop objects onto a left out icon.

"Leave out" is anachronistic: AFAIK Ambient doesn't put any kind of pseudo icon in the original file location so a user might see an empty directory, decide to delete it and then find the left out icon lives there.

I've tried using PNG images with an alpha channel for the panel background but MUI doesn't support this.
