Arr	{length=16 ptr=0x000002023ef60900}	int[]

It is quite verbose!

I have 3 suggestions:

Arr	{&0x000002023ef60900#16}	int[]

and if array is small(say, < 10 elements or configurable)

Arr	{4,1,64,1,4,2}

(could compute the string and if it is < some value(configurable) it disables them.

I'd rather have the ability to setup my own toString that the debugger uses. I have to constantly expand arrays to see the values and there is a lot of verbosity that takes time rather than just a visual glance.
