Feedback / testing is needed on this.
Some small button location tweaks and more importantly, some changes to
bring consistency between the Potion maker screen (already in openmw),
Trading screen (already in openmw), Spellmaker screen, Travel screen and
Training screen. It's mainly the top bar I'm talking about and
resizability.
It is not 1:1 towards vanilla, but looks better (IMO) and again, creates
some consistency. This can probably be expanded to the remaining screens
such as Enchanting and Spell and perhaps even the save/load screen to
have OpenMW wide consistency.
