If it is the width of a particular View's Panes that is bothering you, because you can't see enough of particular long values in one of the Panes, you should really try making it show the Panes on the Left (particularly if you have a Laptop screen with relatively small vertical real-estate).
When you do this, the Panes still auto-size. However, they now auto-size
vertically, instead of horizontally. This limits the
number of values each category can show. But, the Divider Bar separating the Categories and Panes panel from the File List panel now lets you adjust the
width of all of the Panes (which lets you see more of long values in a particular pane). You can even "dock" the Divider Bar over and cover up the File List panel entirely, and have the
full width of MC to display those values in the Panes.
This is easy to do and try out. For any Standard Media View, simply right-click on the View in the
Tree and choose
Customize View. In the dialog that appears, under
Settings on the right-hand side, set
View Details > Panes to
Left (or
Right) and click
OK.*
I don't usually prefer this style, but it does come in handy for some of my views with particularly "big" values (like browsing by file location, for example).
* Note: If the View is locked (which you can also turn on and off in the same dialog), it will prompt you to overwrite the existing view or save the changes instead as a new copy of the View.
