When enabling all logging options ("show categories" and "advanced fields") and disabling "advanced fields" again, the category column stays very wide which ist confusing. The width of this column and of the whole table should be adapted when other columns are removed.
This seems to be a bug in Qt ( https://bugreports.qt-project.org/issues/?jql=text%20~%20%22qtableview%20resize%22%20ORDER%20BY%20status%20DESC ). Setting target milestone to "unspecified".
According to the Qt bug tracker this problem is solved in Qt 5.2 by using QHeaderView::setResizeContentsPrecision
When we are upgrading the minimum required Qt version to 5.2 this should be solved.
