Energy tick
- Proc filter: the tick line now ignores extra energy from Combat Potency, Relentless Strikes, Wolfshead Helm and Furor. It spots them in the combat log, where normal regen ticks never show up. If the log reports a proc a moment after the energy lands, the line snaps back.
- Fallback rule: a single gain at the wrong moment no longer moves the line. It only moves if a second gain lands in step with it 2 seconds later.
- Coming back into cat: turning off "show in bear" or "show out of form" no longer makes your first energy back in cat look like a tick.
- I ran 2 minutes of simulated combat-rogue fighting with 65 Combat Potency procs through the tick code. The old code drifted up to about 1 second off the real ticks. The new code stayed exactly on them. With the combat-log filter switched off, the fallback rule alone was at worst 0.43s off.

Shapeshift cost
- Each profile switch used to rebuild the layout 2–3 times; now it's once.
- The font is looked up once per layout instead of once per icon label. Each lookup went through hundreds of fonts from WeakAuras, Details and DBM.

Smaller items
- The powershift marks on the mana bar are only moved when they actually change, instead of 20 times a second.
- Blinking icons now update every frame instead of 20 times a second, so fast blinks should look smooth.
- The tick is no longer calculated twice per update.
- The code line with two statements run together is fixed.
