SUMMARY I think it would be great if RSIBreak can auto-suspend itself when a certain application is running - think gaming when RSIBreak can completely ruin user experience.
For the time being I am happy with what the documentation (https://docs.kde.org/trunk5/en/rsibreak/rsibreak/general-use.html) suggests - using DBus. E. g. a simple script run every minute by cron: if pgrep '^(supertuxkart|jumpnbump|torcs|foo|bar)$' then qdbus org.kde.rsibreak /rsibreak org.rsibreak.rsiwidget.suspend else qdbus org.kde.rsibreak /rsibreak org.rsibreak.rsiwidget.resume fi
