/*
 * ShrinkVertically -- mark the two vertical-collapse menu items so it is obvious the
 * behaviour comes from this plugin and not from Kanboard core.
 *
 * Core renders these labels in app/Template/project_header/dropdown.php:
 *   .filter-vert-collapse .filter-vert-toggle-collapse  ->  "Collapse vertically"
 *   .filter-vert-expand   .filter-vert-toggle-collapse  ->  "Expand vertically"
 *
 * We append a "+" to each so they read "Collapse vertically+" / "Expand vertically+".
 * This is locale-independent (it edits the rendered text, not the translation table).
