From 219ad8e56ce181cc31d83ceb8ef289863bb737bb Mon Sep 17 00:00:00 2001 From: Levi Neely Date: Thu, 8 Oct 2026 09:35:27 +0200 Subject: [PATCH] Radial: load user config from XDG, fall back to built-in RadialConfig::load() reads $XDG_CONFIG_HOME/olliepalette/radials.json when present and non-empty, else builtinDefault(); a broken/empty file also falls back so the user is never left without radials. Add userConfigPath() and loadFile(path,&error). setupRadials() now calls load().
