Debian is the Universal Operating System and we want to run it on our mobile devices. What are the apps a mobile user needs, and what is the state of readiness in Debian of these apps?

Things to look for:

• Works well on small screen (main window, but also dialogs such as preferences)
• Works well on low-resolution screen (such as 480x272 pocketCHIP)
• Works well with only left clicks (single touch screens)
• Works well with no keyboard (some devices need to use precious screen space for onscreen keyboard)
• Supports gestures where appropriate (scrolling or dragging/swiping)
• Supports multitouch gestures where appropriate (pinch zoom, etc)
• Resource efficient (low-RAM devices)

Things to document:

• Configurations that make the mobile experience better
• Work still to be done

Apps

• EBook Reader: fbreader -- works well on small screen, even with low resolution
  • ~/.FBReader/ui.xml for pocketCHIP: attachment:fbreader-ui.xml
  • Maemo platform config: https://github.com/geometer/FBReader/blob/7abc80d12fab06b05ea1fe68a0e73ea5e9486463/zlibrary/core/data/default/config.maemo.xml
• XMPP: gajim -- works decently on small screen. Low resolution all windows fit except for the "account settings" window
  • ~/.config/gajim/config for pocketCHIP: attachment:gajim-config
  • ~/.config/gajim/pluginsconfig/roster_tweaks for pocketCHIP (for use with roster tweaks plugin): attachment:gajim-roster_tweaks
  • Snags: without a keyboard, there is no way to show/hide the roster in single-window mode, or to show/hide the menu bar. The menu bar is quite small on a low-res screen, so it is best used with a keyboard. Tabbed conversations can become hard to navigate if you have many open. Need to double-click, click+enter, or right-click to open a chat -- usable on single-touch, but not ideal.
    • Auto-join MUCs you have left are re-joined on connection blip: https://dev.gajim.org/gajim/gajim/issues/8361
    • No way to show/hide the participants panel in a MUC: https://dev.gajim.org/gajim/gajim/issues/8352
• Bible: Xiphos is probably our best bet, if you hide all optional panels it seems fine for small-screen use. Currently all windows will not fit on a low-resolution screen, though at least the main window can (https://github.com/crosswire/xiphos/issues/812) with a very small patch
• Web browser -- pocketCHIP uses surf and you keyboard heavily. Works ok. Maybe firefox? They had a Maemo build back in the day, but it's been abandoned. I see reports online that at least basic touch gestures can be set up with it.
