1- Ability to switch between MySQL or Plain Text (Plain Text would log to /logs/ChatLog)
2- Ability to choose between Clean Dates or custom date formats. (For point #1)
3- Ability to set server names (To easily distinguish logs)
4- Ability to log all SourceMod Activity (Commands, Console Commands, RCON, Chat Prints, etc).
Other than that, awesome job and keep it up!
Small recommendation: Learn some Bootstrap 4 as it's super easy to setup for Web Development (I personally find it easier than the rest of the Frameworks out there)
