+# Future Ideas
+
+## Script runner / installer
+
+- **Problem:** Manually symlinking each script to `~/sbin` is tedious
+- **Idea:** A `scripts/install.sh` that symlinks all scripts in `scripts/` to `~/sbin`, with `--dryrun` support naturally
+- **Open questions:** Should it handle removal of stale symlinks? Version checking?
+- **Depends on:** Having at least 2-3 scripts to justify the automation
+
+## CI test runner
+
+- **Problem:** Tests are only run manually
+- **Idea:** Gitea CI action that runs `tests/run-all.sh` on push
+- **Open questions:** What runner is available on Gitea? Docker-based?
+- **Depends on:** Gitea CI being available (cluster-bootstrap M10)
