First post on here so might as well make it a useful one
Resource Summary Toolbar
Ok, at the top of the screen you have your Settlers summary and next to it a list of different resources (Tools, Coins, Pine Planks, Hardwood Planks, Stone, Marble) and then gems. Suggestion is to allow this list of resources to be changeable, so you can monitor other items such as Bronze Swords or bread, or provide a couple of 'open' slots that you can select specific goods for.
Quick Buffs
In a similar thought pattern to the above, could we have our workyard buffs as icons in the top (or bottom) bar too. I know that it's pretty simple to click on the star menu, but this would make applying buffs quicker, especially if you're buffing friends.
Building Placement Overlay
When I go to transfer my General's Garrison, I get a green overlay of all the valid locations. Could we have something similar (yellow) when we're building? Additionally when you're placing a Storehouse, could the area around it be highlighted different colours based on the distance away (gradiented green to yellow). This would make placing Storehouses a lot more efficient in the long run and make it much more graphical to new players what impact the placement of buildings makes (which is quite an important part of the game).
