MyWallet 1.1.1

A fix release: smoother screens with a long history, a message for entries saved outside the dates
on screen, and safer restores. No new features.

Smoother with a long history

• Saving an entry and opening the Transactions list no longer freeze the screen when you have
  thousands of entries. Transactions, Tracking and Home now do their work in the background.
• Home shows a loading state on a slow start instead of briefly saying your wallet needs an
  account.

Entries saved outside the dates on screen

• When the Transactions list is narrowed to some dates and you save an entry for another day, a
  message says so, for example "Saved for Oct 8, outside these dates". Tap Show to move the list to
  that date. This fixes the known issue in 1.1.0.

Problems with stored data

• If some data cannot be read, Home and the Transactions list say so instead of closing the app.
  Your data is not changed, and you can still export a backup from Settings.
• A backup that holds entries this version cannot read, for example one edited by hand, is refused
  before anything is replaced, so your current data stays as it was.

Other changes

• The blank strip above the bottom navigation bar is gone, with both gesture and button
  navigation.

Upgrading

• No database change. 1.1.1 installs over 1.1.0 and keeps every record. Export a backup from
  Settings before you update, as with any update.
• Backups move freely between 1.1.0 and 1.1.1.
