SSL certificate configuration & more

This release adds support for supplying custom SSL certificates to use in requests.

It also adds "focus shifts" - new configuration options to switch focus in response to events.

Here's how these new options look inside config.yaml.

focus:
  on_startup: collection
  on_response: tabs
ssl:
  certificate_path: 'absolute/path/to/certificate.pem'
  key_file: 'absolute/path/to/key.key'
  password: '***********'

A couple of tabs have also been renamed. Metadata is now called Info, and Parameters is now called Query.

• Adds support for specifying custom CA bundles (3 new configuration items inside ssl config section)
• Adds "focus shifts" - configurable automatic focus shifting in focus config section:
  • focus.on_startup to choose which widget gets focused on app launch.
  • focus.on_response to auto-shift focus on receiving a response.
• Fixes jump mode issue when initiated while an input field was focused.
• Remove focus from the screen below the jump overlay while the jump overlay is active.
• Renames Metadata tab to Info
• Renames Parameters tab to Query
