mention sampler expand button

[RafaelFrance]

2.4 manual. Chapter 3.4. Samplers.

I do not found where is located in the manual the button to toggle the "Sample decks expanded".

Two difficulties:

• this button is difficult to see.
• the label of this button is wrong. Same label that button to toggle samplers section (on top of Mixxx interface).

So we need to add a hint to the manual: "The sampler section maybe collapsed. In order to see the full sampler you need to click the Expand button. In LateNight it is located at the center of each samplers row"

• this button is difficult to see.
• the label of this button is wrong. Same label that button to toggle samplers section (on top of Mixxx interface).

These are GUI issues. Do you mind filing a report for each at https://github.com/mixxxdj/mixxx/issues ?
