In the V3 panel, there are several logfiles visible in the log section.
Some of them you can open and view. For some others you get a "permission denied" because they are owned by root. Development says this is working as designed. You can only open them in SSH.
However, this works confusing, when you see logfiles in a panel, you expect to be able to open and view them.
So the request is:
1.) Change the logfile's owner or group rights, so every displayed log in the panel can also be opened and viewed from withint the V3 panel.
if this is not possible then is my suggestion:
2.) Change the display in the V3 panel, so log files which would give a "permission denied" are not displayed in the panel under logs anymore, which is more decent and also prevents confusion.
