So I'm a bit surprised for a game that feels and plays relatively polished, and certainly the least broken Civ released since forever, this game has some really weird UI quirks that seems like it was intentionally done a certain way only to be patched out later. Here's my list. I'll add/subtract to this list as people post theirs and clarify things I may have missed. General UI Tooltips- The game does a good job of showing you where to best place a new district based on adjacency bonuses, but there's no way go back and review the yields of existing districts as you improve and increase their yields over time to follow up on results of planning Tooltips - You have to click on the citizen icon to deselect it to exit citizen management screen; this seems awkward. Hitting ESC does the same thing but more often than not, I pull up the settings (save/exit) screen as well, breaking the flow of a game Tooltips - Factories/Power Plants/ Arena/ Zoos and other buildings with area affects should either have their own filter or a tooltip showing their range for better city planning Tooltips - Hex view is too mild even when turned on. Request adding a new setting to increase opacity of the hex borders. Tooltips - There is generally too much 'hovering' to find needed information. Victory Condition reports should instead include a ' +' and '-' clicky to expand information provided. There is absolutely no reason why there is no screen for military size listing each Civ's strength in order, or beakers per turn for the science screen. Log - There should be a diplomacy log summarizing diplomatic/traveller's reports from all the nations each turn Log- There should be a separate event log Log - both logs should keep something like the last 10 turns of events, not just 1 turn Wonders - The 'X' to exit out of a wonder screen and space race rocket launch screen is oddly placed far to the edge of the screen. This was likely done for aesthetic reasons. It's fine to keep it there, but hitting SPACE or ESC should do the same and exit us out Log - There is a notification for losing suzerain but appears to be no tooltip for regaining it when envoys are sent. Both should go into the suggested diplomatic log UI scaling unavailable at 1440p ( people are using workarounds currently) UI font is too small even at 1080p (people are using workarounds currently) Combat General UI- When an enemy unit is in range for bombard, the reticule icon looks weirdly small and muted, it takes a while to realize that the game is prompting me to bombard something General UI - Hostile unit in sight of a city/unit's LINE-OF-SIGHT should generate a notification that goes into a notification log General UI/Unit commands - There is no sentry function for units to alert players when enemy troops are near Trade Trade routes- Trade route can filter by type but cannot sort by yield Trade routes - similarly, when deciding on where to send a new route, there should be a way to sort by yeild (gold, production, food, faith, etc) Trade routes- When a trade route completes, there's no tooltip telling you which route the trading unit just completed Trade routes- There should also be an 'assign to last' function for trade routes Trade routes- Hovering over a trading unit doesn't show it's route. The graphics are certainly there as you see it when setting up a route. Resources Resources- Luxuries and Bonus resources are listed together under the resource tab in reports, why are they not separated? Resources - There should be a report showing which city is benefiting from the amenities provided by which luxury Resources - UI should make it clear excess luxuries provide no additional benefit and show them as tradeable Strategic Resources / city build - It's not clear which unit requires how many copies of what resource to be buildable , hovering over a resource on the top bar (the banner) of the screen should show all researched/available units that are buildable and not buildable with the existing resources on hand as the tooltip that is currently there adds no new information. Terrain & Unit Hills are not often obvious Hand off between a unit that is out of MP to the next unit is awkward, often resulting in the player moving the next unit to weird places because they thought they were moving the previous unit. Bugs Counterspies will keep promoting even after their 3rd promotion and the spy cannot gain any more promotions, forcing players to reassign them to the city each and every time. There should be 'assign to previous city/assignment' button in addition to removing notification of a promotion after they are maxed out. When using hex view *show hexes* under certain conditions the borders will disappear all-together. Going back to reset 'show hexes' will fix the problem. City will show second to last item built instead of last item built when finishing something Edge-of-screen scrolling doesn't work when a side window is open.
