It would be helpful if you can view the following stats of each character you own without switching characters like how it is done while checking the inventories of each character.

1) lifeskilling levels of each character.

2) level exp and skill percentages.

3) gear durability, so when a gear gets posted on the central market, you can view how much you should buy. By the time you change characters and caluculate the item might be gone.

4) total inventory slots and weight capacity.

5) breath, strength and health exp.
