Long time lurker here but just had to post a positive review of this. I've been tinkering with developing my own plugins and this is what I needed to make things much easier to debug. The UI looks nice and can be moved around and resized, plus the ability to filter, group messages, and hide/show message types is so useful. Can't recommend this enough - even to casual users this can be used to identify issues with some plugins you may be using that would normally be hidden. This could leave some plugin devs red faced - the number of hidden error messages being spammed repeatedly with just a single plugin enabled can easily exceed 1k in a matter of moments. Many thanks for this!
