Modifications to Estuary

Hi,

I just want to make some modifications on Estuary for things that I find annoying. When I view a movie and press pause appear some controls up and down in the screen. When I start again playback those controls have a delay about 3 seconds to disappear which is very annoying and unnecessary, especially when you are using subtitles. Is it possible, just modifying an xml file, to remove this delay? To have an effect like in confluence?

Also in fast forward these controls appear again with the same effect. Is it possible to cancel their appearance through some xml modification?

Thanks for any help.
