// we're intentionally displaying the launcher title and icon instead of the target,
// e.g. you want to make launchers to 2 mermaid diagrams which both have mermaid icon (ok),
// but on the launchpad you want them distinguishable.
// for titles, the note titles may follow a different scheme than maybe desirable on the launchpad
// another reason is the discrepancy between what user sees on the launchpad and in the config (esp. icons).
// The only downside is more work in setting up the typical case
// where you actually want to have both title and icon in sync, but for those cases there are bookmarks
