Please provide column hiding in Options window

[vsrawat]

Previously, fr options window had method to show and hide columns, so we could hide columns that we don't find relevant for our work.

In web extension version of fr, Options open in a new tab and all columns are always visible, giving a feeling of "cramped screen" in seeing things not relevant for us.

If possible, please provide column hiding in Options window, the way it was happening earlier.

Thanks.
