User Feedback

While erasing the offset value from the tracing tool the crash occurred.

I think it might be because with the 'x' button in the editfield sets the value to NULL and not 0.

'x' Button in editfield only appears when a value other then 0 is entered.

I cannot say I'm really happy with the solution (which was to remove the clear button from this particular widget), please check the PR comments for some more context.
