Navigating in Navigation view in Power should be easy. For efficiency in navigation the columns should autofit what is in the column. Otherwise, you have to use the sliders to move across the columns to see what is in them, each time adjusting the column width.
The column width in Meridian PowerWeb can be set by individual users. The column settings are stored in the user profile and kept for the next session. We decided not to implement the autofit width option in PowerWeb columns, because some columns i.e. description or title can take up to 255 characters.
