v4.34.0: Rotmire timers for the new Sporefall raid
Cooldown timers for Rotmire, the first boss of the new Sporefall raid, are now in the planner on Heroic and Mythic.

feature
One of your most-requested features. Top Comps shows the roster behind a top Warcraft Logs kill for any Midnight Season 1 boss, so you can pull a guild's cooldowns straight into a note.

update
The Weekly Vault chest on the Setup page now counts each of a member's characters separately, so an alt set to play a few bosses shows its own vault progress instead of being lumped in with the main.

feature
A new Quick Fill toggle fills an assignment row one player at a time, like the old planner did, while keeping the grid's fixed slots. Also improved the Gear Upgrades table and added clickable death markers to the WCL Compare timeline.

update
Small spacing and color changes to the planner timeline: the spell list and the timeline are now their own panels, with softer colors and more room to breathe between rows.
