Heya! For a long time I did not write on lua so I have questions and a lot of them Sooo got idea (or mb its some request and question) make some changes for several add-ons so that they look alike (or something like).
1. First - we have DarkUi Light theme with clean action bars edges now.. Can we make clean edges for Greymind Quick Slot Bar and AlphaGear 2 (Gear Icon/Weapon Icon) ?
2. Second - we have Foundry Tactical Combat (FTC) - CC
a. Vertical party frames... any changes for make them horizontal and unpin for every party member (free moved anywhere on the screen and scaled in size)?
b. Make player(&target) frames with texture (like party frames).
c. Castbar ???
d. Frame texture like
3. Third - target nameplates and as y see on the top left buff visual example -
I don't know, if I got you right. But as nobody else answered so far:
For changing textures the RedirectTexture function would be used.
For the other things the addon zgoo with /zgoo mouse is your friend.
And reading the ESOUI Source is very helpful.
