Yes. The pitch feature is pushing the envelope in many aspects, which has impact on other parts of the behaviour.

Yup. The time shows elapsed real time and makes no compensation for faster or slower playback. We could try making a crude adjustment using the pitch percent.

Yes. This happens if you for example hold down ON+UP and release them simultaneously. I'll see if I can fix that.

It was actually intended behaviour. The reason I implemeted delayed drawing of the on screen is that otherwise the screen flickers annoyingly when you just want to go from the wps to the browser.

I've now changed it so the on screen is drawn as soon as you use a combined ON key. This should make it less confusing.
