Buttons explanation
Controls
In tooltip you can see equipment that is currently equipped (cyan), available (white) and missing in inventory (red). If "Test Fit" is enabled, you'll see your character will-be stats when hovering on loadout button.

If "Maximize Stat Buttons" option is enabled, you can extend buttons array by clicking arrow button. There will be displayed stat icons for all stats that can be maximized using available equipment. If there is no button for specific stat, then you cannot improve it using available equipment. Green number will display stat will-be stat value.
If "Test Fit" is enabled, you'll see your character will-be stats when hovering on loadout button.

When holding SHIFT, you will be able to use equipment not only from current character inventory but from all neighboring players. Note that character should have "Share" checkbox enabled to agree with giving you items. If you enable "Always Share" option, no checkbox will be displayed and every character will be able to share his items.

If "Better XP string" option is enabled, game will display XP bar in more detailed format. In example above you can see that it is "155/600 (1755)". Where 155 is experience in current level, 600 is experience needed for next level and 1755 is total XP character have.

If "Display price" option is enabled, for each sellable item tooltip, base price will be displayed. Please note that you'll never be able to sell item by this price in shops. But if character is located in place where selling is possible, this value will be precisely display for how much you can actually sell it.

If "Display poison turns" option is enabled, you can check how many turns left until it wears off.

Sometimes it is unclear if encounter will remain on map after you visit it. So, if "Highlight one time encounters" option is enabled exclamation mark will be added to encounter name as well as small footnote on encounter screen.
(on screenshot it is displayed incorrectly - I changed encounter definition for demo sake)
