Better setting of long-press time
So… there is this setting in Settings -> Typing -> Keys -> Long-press time which let us to configure delay after which an extended pop-up will show up and it's configured in the range: 100ms - 1600ms.
However - for me everything above roughly 300ms is simply too long and I quite often use symbols or diacritics (unfortunately your predictions for Polish force me to correct the endings quite often, and there is also need for basic symbols). and given the scale, selecting something around 150ms is quite difficult.
It would be nice if there would be different scale or possibility to enter the value manually (for example by tapping on the display value of current selection)
