Operator Panel, values/tweek options don't show up some issue is bothering me for a while now. I could manage to work around it but i realise that I'm missing some options.

What I usually see in tutorials is that the options/values of a specific options, lets say, the bevel tool in edit mode (ctrl+b), will show op in the operator field. 

Most of the tools I execute, the tweakable values/options, don't show up, or in the bar below:

Thanks in advance]1
Operator options show up in the Redo Panel after the operator has been executed.

If the operator is cancelled instead of confirmed, no options will appear as no operator has been run (even though an operator was started).

Your screenshot shows the operator is running, but not yet finished/confirmed.
