You may freely redistribute UV with your own saved settings. Additionally, if Lister plugins' authors give your such permission, you can also include preinstalled plugins into your package. It's recommended but not required to include also help and language files.
Here is a tip helping you to create a custom UV package with plugins. UV sets "ATViewer" environment variable on start, which refers to the application folder. So you should preinstall all needed plugins into "Plugins" subfolder of the UV folder, and then write their paths in the "Viewer.ini" configuration file like this:
[ListerPlugins] 0=%ATViewer%\Plugins\OOoViewer\OOoViewer.wlxIf plugins are preinstalled in such way, you can pack the entire UV folder, there should be no problems in plugins usage after you unpack your distributive on another computer.
