Topic: add build-in capability that allows to paste directly a list of column names -from clipboard- in column dialog filter.
Today's workaround: as of today, I did a script that takes the clipboard content -loaded with column names- and converts it into a regular expression. Then, I paste this regular expression in filter and I select 'regular expression' filter mode. This works but is a bit painful.
I use this often when working with 'column switcher', but I assume this may work for many other needs.
