What is the option to make by default all objects expandable?

[greenozon]

Pardon this stupid question, what is the option to make by default all objects expandable?
instead of seeing these "..." all around

IL used:
ILSpy version 7.2.0.6843-rc
.NET version 4.8.3928.0

Great answer! thanks a lot

but I"ve got another one while I was testing your hint

so, if for example I'm having the "..." state and then I click the "Expand member definitions after decompilation" checkbox
then click OK - nothing happens!

Expected result - collapsed functions should get expanded right after OK
Currently I"ve to click on another class, then back to current one - only then it works ...

Why I' thinking this way? cause for example if you click the "Show line numbers" then OK - it is applied right after OK click..

Maybe it worth to do immediate action for all the checkboxes in Display section of Options?
