You can run multiple instances of the application given that they have different session names.
To start new instance with test1 name, run:
copyq --session=test1
This instance uses configuration, tabs and items unique to given session name.
You can still start default session (with empty session name) with just:
copyq
In the same manner you can manipulate the session. E.g. to add an item
to first tab in test1 session, run:
copyq --session=test1 add "Some text"
Default session has empty name but it can be overridden by setting
COPYQ_SESSION_NAME environment variable.
Icon for each session is bit different. The color is generated from session
name and can be changed using COPYQ_SESSION_COLOR environment variable (the
color to override can be set with COPYQ_APP_COLOR environment variable).
COPYQ_SESSION_COLOR="yellow" copyq COPYQ_SESSION_COLOR="#f90" copyq
