When writing code and delivering to customers you usually will find your self (or someone else ...) debugging your code throw log files and probably a lot of them.
I know I do :)
So I wrote my self a small helper tool based on Electron and vue.js + vuetifyjs. which makes it cross-platform.
And I made is open source just for you :)
You can just drag and drop you files on it and start 'finding' , setting colors for specific phrases or filtering in or out any phrase you like.
BTW I used this cool template code from github, to get started easily...
Just note that this is a work-in-progress, feel free to file in issue you find on github :)
