enh(ui): make the SParameters components more tactile friendly


The SParameters components were hard to interact with in a touchscreen context. These changes make them bigger and make it easier to interact with.

Closes #945 (closed)

How to test it?

Open any application which uses SParameters, check it still works and the changes are applied.
