Hi zero-13, someone had a similar question not too long ago, check out here for some discussion:
http://moi3d.com/forum/index.php?webtag=MOI&msg=9953.1

It is possible to disable palette collapsing, however when they collapse it's because they're taking up more space than is available in the window and the alternative to collapsing is that you'll have a vertical scroll bar and you'll need to scroll up and down to get at some of them.

So the collapsing is handled in a script file SidePaneTabs.js which is in the UI sub-folder inside of the app install folder. There's a function in there named CompactPaletteHeaders(), if you edit it to place a return; statment as the first thing in it, that will effectively disable the auto collapsing. So you want it to look like this:

function CompactPaletteHeaders( HeaderToIgnore )
{
         return;

          <.... you can leave other stuff below it ...>

But then you'll need to do vertical scrolling instead. The collapsing exists to keep tabs on screen so that you can go to them without needing to scroll around.

Hi Michael,

I definitely understand the reasoning for the collapsing behavior, and it is indeed superior to scrolling, I’ll leave it be and subdue the old OCD monster with the facts. :)

Thank you for your reply and solution!
