 - mark generated via meta so other files in the dir can be created, deleted, replaced safely
+- links like `/Smoktests` in user-files home wiki don't rewrite
+- map fullURLScraped->internalURL for relative links sometimes
+- scrape odo
+- rewrite links if available to local
+- anchor per line
+- anchor links work
+- ui; last updated; 2022.02.01T12:34:56
 done:
+- gitlab/-/blob/about.md does NOT map to exactly 1 file
+- crawler does NOT modify title cause readme.md everywhere
+- use `meta` so no need for extra level for explicit single files
+- table of contents
+- min-height for easymde
+- /ui/files does not redir in b1
+- anchors on gitlab wikis at least are bad
+- gitlab wiki original links are empty
+- /ui/files is an about page over a redir
+- use `read-only` for autogenerated things;; could skip easymde and make google docs much faster
+- new line after original link
+- scrape gslide
+- scrape gsheet
+- scrape gdoc
 - alert box; https://concisecss.com/documentation/ui
 - hide checkbox for tree
 - do not rewrite .md title vs. link cause hrefs to ./gobs.md wont work
