Is there a config file I can edit, rather than re-saving all my many listers? Thank you.
If you mean lister layouts, you can find all the config files by typing
/dopusdata/Layouts into the path field in Opus.
Each layout is stored in a text / xml file in or below that folder, so you can use search & replace in a text editor to modify the sizes/positions if it's easier.
It's a good idea to make a backup of the files before editing them, in case the search & replace doesn't go as planned.
You should not need to restart Opus for the changes to take effect. (You do with some config files, but not layouts.)
Thank you sir!
edit: Hey I made a lister to the /Layouts folder for future
