Is your feature request related to a problem? Please describe

A clear and concise description of what the problem is.

①Please add an option in the config file to disable the custom window‑title feature.
②In my test environment, even with "customIcons=false" , my window icon is still replaced by a dirt block. That setting appears to be broken.

Describe the solution you'd like

A clear and concise description of what you want to happen.

When I include both Valkyrie and ITLT in my modpack, they both modify the game’s window title and icon, which obviously conflicts. For various reasons, I prefer ITLT’s custom icon/title functionality, so I have to forgo using Valkyrie—despite its excellent performance optimizations. I’m very happy with Valkyrie’s speed improvements and really want to keep it in my modpack. Ideally, Valkyrie would focus solely on performance tuning: remove all non‑optimization features, rather than simply offering a config option. From what I’ve seen on various forums, Valkyrie’s non-performance optimization features either conflict with mods like OptiFine or have better alternatives, so players usually disable them entirely.
