Freeciv-web is a HTML5 version of the strategy game Freeciv which uses jQuery UI v1.11.2. I've been developing this game for quite some time now as an open source project on Github .

When asking for feedback from users, most of the users say that the user-interface is very bad. Some say that the UI is clunky and unintuitive. However, experienced Freeciv players are able to withstand the UI.

Since jQuery UI is a very important part of the UI in Freeciv-web, I wonder if users in this jQuery UI forum have some suggestions about how to improve the user interface. How can I make this game more user-friendly?
