Plesk Obsidian introduced the Dynamic List View Mode, is it possible to set this as the default?
Yes, it is possible to define a default view mode by editing the panel.ini and adding the below lines with the desired option; 'dynamic', 'active' or 'classic':
forceWebsiteList = dynamic
Furthermore, if only specific views should be available to the users, add below line into the 'panel.ini'
[navigation] section to hide unwanted view modes, e.g. 'active' and 'classic':
hideWebsiteList = active, classic
Note that the change applies server-wide, if needed to be applied individually for example per service plan please vote for such feature in our Official Plesk UserVoice channel. Top-ranked suggestions are likely to be included in the next Plesk versions.
