I too have modded my own Drox a while back for the following:
--smaller buff / debuff and weakness icons. I use horizontal icons no text.
--smaller hotbar icons allowing more hotbars across bottom of screen.
--2 extra horizontal hotbars which can be toggled through the Drox settings window just like the rest.
--added one more tab to infomaps detailed map page to list all the buffs that we as a guild push up for our raids and their corresponding locations.
Have a look
Not sure I would be allowed to upload my files here and conflict with the Drox version here since I basically modded from that and made it my own.
Kind of like hacking the roof off a Cuda and lowering it. It is still a Cuda,, but more personalized.
But feel free to contact me --firstname.lastname@example.org
-- and I wil be happy to email the files or attempt to mod the files that you use.
Edit ***Attached are 4 files that I modded to suit my desires.
Icon Buffs/Debuffs Horizontal --Drox_IconBuffsAndDebuffs.xml
Icon Target Debuffs Horizontal --Drox_IconTargetDebuffs.xml
Horizontal Hotbars for 2 additional bars all with smaller icons --Drox_HotbarsHorizontal.xml
Control panel so that you can toggle them --Drox_ControlPanel.xml
