Hi Miggi,
In the future, please start a new topic for each question, thanks.
Go into the menu in a ladder and choose Layout - Save as Default. The settings will then apply to all future ladders that you open.
There is also a Default Stake setting in the main windows settings. Go to File | Settings | Staking tab.
Yes, market overview graph is on my list of features that I hope to add in the future
Kind regards,
Gavin
