- Input elements now look and feel consistenly more simple, metal-like.

  (e.g. math-output-area and other pointer-areas)

Administratives:

- improve add-tag dialog (in note-timeline-view)
- consolidate styling of links (hrefs) and buttons (clicks)
- load more posts automatically

  (also add "load newer posts")
- tag-filter-view, login-menu and user-menu still interfere
  (if screen-width is not so wide needs revision)
