Design Philosophy:
MonoBar is designed for DPS/Leveling/Solo but flexibility is based more on your ability/willingness to customise.
Focused on keybinding, with macros hidden in mouseover/faded actionbars at the bottom.
Minimalist aesthetics but with all useful information presented clearly and with least eye-travel from the character zone as possible.
eg; I don't need to know my own name but I do need to know if my HP is low hence the removal of name text from player frame.
Raidleading/Tanking/Healing is easy enough with this but you will want to activate some features and make sure you install your preferred addons for each role.
Features:
Full UI requires just ElvUI & Shadow and Light
Buff tracking next to minimap as normal.
Procs on main frames centered as much as possible with whitelist only filter.
This requires manually adding all the spell IDs you wish to track but the clean look and visibility of short term buffs/procs is worth the effort.
(see mage screenshots: this list tracks just 'Heating Up' and the actionbar glow is the visual cue for 'Hot Streak').
This solution is less polished than WeakAuras but much easier to configure and doesn't require the extra addon.
Other addons in use:
Leatrix Plus (misc automation and tweaks)
Details! (combat log)
Designed to closely mimic my SUF based UI.

Should be class and resolution agnostic.
Suggestions welcomed.
They will be more likely to get done if focused on minimalism and clean aesthetics.
