[Feature Request] Progress Indicator (Bossbar) making all online members aware

[tooobiiii]

Good idea for this one:

[Essential] Team Members who are online and on the island wont know when the block phase ascends. Maybe show the Title to all memebers on the island or introduce a Bossbar withprogress for players on the island

I like the boss bar idea.
