Yes.  So this is a technical limitation of using the ToolBox class from
vcl to manage the horizontal layout of the controls (inherited from the
old implementation).  ToolBox can only manage controls horizontally, but
we have little control over how it manages them vertically.

Noel and I discussed this, and the plan is to create our own container
Window to replace ToolBox in order to have more control over the
vertical placement of the child controls, to fix issues like this.  But
since doing that would be quite invasive, we may have to forgo that for
3.5 and wait until 3.6.  It's up to Noel.

Yeah.  To me, the way it behaves currently may not be perfect, but is
reasonable & it was a conscious decision that we (Anurag and I) made
before Noel took over, based on the technicality (it makes the
implementation simpler) and the way our competitor behaves.  Of course,
if there is room for improvement I'm all for it, but different people
may see different optimal behavior for this, so it would be good to have
a good, detailed analysis from the UX side before making any changes.

AFAIK there is no real reason except that we simply inherited this
behavior from the old implementation.  Excel has the same limitation
interestingly, but that has nothing to do with our decision (or lack
thereof).

There may be a real reason why this limitation existed, but I'm not
aware of that at the moment.
