Things I'd like done - or work on after I retire:

• web browser (most likely chromium fork, firefox is less memory hungry but no e10s or tab unloading and other things that make it slooooow with many tabs):
  • that seamlessly blends tabs and bookmarks, as many packrats like me tend to abuse tabs as bookmarks and accumulate hundreds of them
  • working and reliable vertical tabs
  • “power saving” mode when on battery
• ultimate maps:
  • mapy.cz tourist lookalike renderer for openstreetmaps
  • googlemaps-compatible API for mapy.cz
  • traffic level scraper for googlemaps + overlay for mapy.cz or osm (tos violation)
  • photo layer for googlemaps to universal overlay (tos violation)
• linux application-level firewall with interactive gui
• fc: a tool like mc, but single-purpose and streamlined for just choosing filename arguments for commands (e.g. mplayer playlist composition)
• ipython is awesome, but sucks for long-running computations https://github.com/ipython/ipython/issues/4140 (either fix the issue, or create a screen-like frontend)

I also like a lot of jenda's ideas.
