Hello. Thank You for developing this one, it really works great and so far it's suiting me best. Since there is active development going on i decided to open a request for:

→better global speed handling – to have (for instance) a switch or something to remember next videos on current speed or apply for current only
→configurable values and number of values in preset board – to display less or more pre-configured ones and to customize their values
→click on timer icon to reset speed to 1.0
→add ability to show/hide indicator elements – yes, even more than now
→work for all yt videos – sometimes indicator is not available on youtube video. i will report exact examples in the future, unless it's a known issue?
