I have been making changes to the poweroftwo UI to make it more suitable for use on widescreen monitors (since I use one) and as a result have made some extensive changes to the layout of some textures and the EQUI_Animations.xml which I would like to reflect back into the poweroftwo default release.
The changes are mainly as follows...
1. Gauges broken out of pot_windows.tga into their own file
2. Icon backgrounds such as BlueIconBackground, SpellIconBackground etc broken out into their own file
3. pot_buttons.tga and pot_windows.tga extensively reshuffled to make better use of the vacated space and pot_windows.tga reduced in size
4. Every gauge on a window made more efficient and easier to read
5. EQUI_HotButtonWnd.xml widened, 12 quick click slots added for (currently) 8 primary inventory slots plus pri/sec/rng/ammo and player stats, resists, xp and aaxp displayed but all removed from EQUI_Inventory.xml
6. Percentages added for XP, AAXP, health, mana, energy and group member health
7. F2-6 added on group window
8. Buff window has been changed to show buff names and better coloured background behind the buffs. This has a knock-on effect on the spell book so the changes have been reflected there too. This would be an optional change in the UI release along with left and right-handed versions and a compact no name version of the buff window.
9. Cast spells window has been enhanced to show better coloured backgrounds to indicate spell type and names have been added. There is scope for several interesting variations here along the lines of compact (as it is now), 64px coloured blocks with no spell names in horizontal and vertical arrangement and the full 128px coloured blocks with spell names and of course left and right-handed versions.
As a result of these changes to the gauges, they have become wider but much easier to read. I have also improved the mini-gauge so I believe these benefits can be retained in the standard version of the poweroftwo UI. For example offering a full-size 128px gauge with useful endcaps as standard and a smaller 64px mini-gauge on permanently visible windows as an optional download for those who need the screen space.
I am not sure how best to document these changes for developers as they are numerous and wide-reaching but I think the result will be well worth it.
Here is a sample screenshot at 1920x1200 of how it looks on my Cleric (some photoshop used to make gauges visible in this screenshot).
