I like what’s there and look forward to using it next time I need to pick apart logs. Something in the GUI library you used for the generic IDB viewer portion isn’t available on my system, though. 
WARNING: package com.sun.java.swing.plaf.windows not in java.desktop
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: com/sun/java/swing/plaf/windows/WindowsLookAndFeel
I’m running Mint (based off Ubuntu 20.04), and had to git clone your repo and do gradlew run locally, so this may just be my setup. I don’t do Java/Kotlin/gradle packaging or building and am kinda lost on where to look in the project to figure this out. Searching online finds other people complaining that OpenJDK on Ubuntu is missing this bit and they ended up building JARs manually to get around it. (here)
I feel like such a killjoy reporting a compatibility issue on a 1 month old project…
