Struct ColumnDef 

pub struct ColumnDef {
    pub id: &'static str,
    pub label: &'static str,
    pub default_visible: bool,
    pub priority: u16,
    pub requires_feature: Option<&'static str>,
}

A single optional column in the MR table.

Plugins register their columns via inventory::submit!(ColumnDef { … }) — no change to config.rs, mod.rs or storage.rs is needed when a new column is added by a plugin crate.

Display order

Columns are sorted by priority (ascending) when collect_all_columns is called. Convention:

• 0–99 → built-in columns (Activity, Target, Labels, Milestone, Notes, Diff)
• 100–199 → first-party tracker plugin columns (Redmine Ticket, Jira Issue, …)
• 200+ → community / third-party plugin columns

Fields

id: &'static str

Unique machine-readable identifier (e.g. "activity", "tracker_ticket"). Used as the persistence key in projects.toml — must be stable across versions.

label: &'static str

Human-readable label shown in the column picker popup (e.g. "Activity").

default_visible: bool

Whether this column is visible by default on a fresh install.

priority: u16

Display order — lower values appear first in the column picker.

requires_feature: Option<&'static str>

When Some, the column is only shown when the runtime condition is met (e.g. a tracker provider is configured). The closure receives a single bool context value whose meaning is defined per-column in the orchestrator.

None means the column is always available regardless of runtime state.
