How can I control the stacking order of objects in appdesigner?

How can I control the stacking order of objects in appdesigner? It seems to be determined by the order in which the panels or axes are created. What if I want an object created later to slide underneath earlier objects?

You can control the order of the 'Children' of a graphics object directly:
fig = uifigure;
panel1 = uipanel(fig, 'BackgroundColor', 'b');
panel2 = uipanel(fig, 'BackgroundColor', 'r');
fig.Children = flip(fig.Children)

I was just copying what you had to show that it works, they were adjacent in the question so assumed it was all in your startup. I wouldn't recommend calling uipanel in startup!
It's definitely a fair enhancement request to have them be adjustable in the component browser on the right.

Yes, intuitively I should be able to drag panels up and down the component browser to order the stacking. It seems like the stack order is tied to the order of creation, which is super inflexible.

Inspired by Sean's answer, I wrote the attached utility for use in the startupFcn:
move_to_bottom(app.UIFigure, app.Axes);

You could also keep a list of handles; e.g. in the variable background and than move all of these to the background.
hfig = uifigure; % create figure
hax = uiaxes(hfig); % create axis
foreground = plot(hax,rand(1,100),'r'); % create red line
hold(hax,'on');
for ind = 1:10
% this moves the foreground plot to the background...
background(ind) = plot(hax,rand(1,100),'k'); % create 10 ack lines (on top of red line)
end
% move the background lines to the background!
ch = get(hax,'children'); % get all plots from hax
[~,neworder] = sort(ismember(ch,background)); % reorder the handles to move the background lines to the background
set(hax,'children',ch(neworder)); % set the new order of all lines

Starting in MATLAB R2023a you can use uistack to control the stacking order of ui components in a uifigure such as in App Designer.
