I found chat disabled.
Noticed the lack of customization with maps, controls, inventory, armory, and the lack of my fleet being displayed.
Most of my Prem ship did not show up.
My eyesight is a little weak these days and the increasing contrast between the island and the water needs to be more significant.
For all the money I have spent on the published version, I think some time would be spent on improving the user interface and inventory. WOWS spends too much time making ships and no time on the interface.
