Stack Bundle Icon Sizing

When using the stack bundle, will the icons resize when I only use 2 tools per stack or is the icon just two sizes, large and small?

I am making this 2x2 stack but the icons are small that you can barely make it out

I believe this is a limitation in the RevitAPI, it only has two sizes for buttons, so regardless of 2 or 3 items in a stack it will use the same small icon size of 16x16.

It can be “hacked” to display 24x24, but not officially supported in API.

Thanks for sharing. At least I know now.
