It'd be great if Turbine were to forgo one content update (if they have to) just to bring DDO's user interface functionality up to modern standards.
In order of preference/priority:
- Viewing each party member's location, and Classes/Level simply by hovering the mouse over their HP/SP bar in the party list. (instead of having to use the Who panel if they aren't visible on-screen.)
- Right-click Context Menus for all item icons (whether they're in the inventory, bank, vendor Sell view, or on hotbars) to let you:
- Examine
- Lock/Unlock or Mark/Unmark as Junk
- Mark with a flag from a choice of colors (for personal organization, as per Alabore suggestion's below. for example Green for me would mean I have to pass those items to an alt later)
- Equip to Left/Right Hand (as two different choices on the menu)
- Unequip (not currently possible through hotbars other than selecting some other item or a blank Weapon Set.)
- Send to first emply slot on Hotbar #N
- Discard
- A private user-editable journal so we don't have to put self-reminders in a publicly-viewable bio
- Window and Hotbar snapping to let us neat-freaks easily align them up with each other.
- Increase the minimum pixel distance needed to move the mouse before you can drag an icon off a hotbar.
- A separate Buffs page on the Character Sheet that shows a vertically-scrollable list of all your active [de]buffs, with detailed info for each in mouse-over tooltips.
- Increase the length of the buff bar for the good number of gamers who use monitors bigger than 17".
- The option to display a smaller party bar, with tiny fonts for the player names and no Class icons or SP bars unless you hover on a name (can take up too much space as it is on small laptop screens especially when you have a lot of hotbars.)
- A special, scrollable hotbar that automatically lists all the potions that're in your inventory, maybe locked to one of the screen edges as chosen by the user.
- Automatically highlight players that're in your Friends list by using a different color for their chat messages, and an icon above their heads or some other marker around them in the main view.
I'll edit this post to include more suggestions/requests from other posters. Thanks!
