There is one thing wrong with Search in all logs feature and encrypted log files. Because when it tells us there was some encrypted log files and we must enter a password to decrypt them, we enter a password but Messenger Plus! doesn't check the correctness of the password. So people always think they entered the correct password even if not. So there must be an improvement about this issue. Let me explain the solution in my head:
I believe that when we press on "Search" button, it firstly searches for files and when it finds some files with .ple extension, it requires us to enter a password for them. But it doesn't (and can't) check all the files about the correctness of the password before starting search. So my solution is, at the end of the search, it will pop-up a new window and ask us like that:
... unsuccessful, this window will appear again.
Is this good?
