Hi, I like your log viewer, it displays the logs very clean.
Here is a suggestion: During initial file open dialog you restrict files to ".txt", ".json" and ".clef".
I have to rename all my logs to ".txt" first to open them, which can be time consuming.
Can you add ".log" as well? Or maybe even better a "." option, because some tools just use their own ending even if the format is correct inside.
cheers
