** [update] No worries - I figured it out. I just needed to be a bit more delicate when moving the tool-bars around. With more finesse they just snap in place, in-line!]
I have made a custom toolbar, with all the things I use regularly on it. I wish also to have the <Search> function visible. I cannot find this function anywhere to add to my custom toolbar (only <find>), so I selected the <Search bar>as a separate toolbar.
However, I cannot get it to align with my custom bar, nor the <menu bar>... I end up with a lot of wasted screen space - with the <menu bar> on top of the <custom bar>, then the <search bar> below that.
Is this a bug, a function or my ignorance?
