Total Commander

Mode.

Some of my view modes set the width of active panel to 100%. I have not found a way to set width to 50/50 again on return to default View Mode automatically.

If the first variant is impossible, please add possibility to run commands when switch from any View Mode to default View Mode

Never thought about this before, but you are right.
Auto run command for default view mode is missing to make the View Mode feature complete.

"... 20.09.16 Added: Define view mode commands when switching away from a view mode to a different mode. Separate by | (vertical line), e.g. cm_100percent|cm_50percent (32/64) ..."

Mr. Ghisler!
Many thanks for implementing!

Important: This function is faulty in the initial release of beta 15: The option is always applied to the left panel only. I have immediately released an update which replaces the beta 15 with a newer one. You can check in menu Help - About Total Commander whether you have the newer version: It should show an (a) behind the release date.
