Hello, binbinhfr!
For me, this mod is absolutely essential. thank you so much. :)
There is one thing an earnest reques.
Make it compatible with the "TimeButtons (by darius456)" mod.
The reason I use TimeButtons mode is for shortcuts.
In TimeButtons mode, if I change the speed, the speed displayed in "TimeTools" does not change.
I don't know how to program, so I don't have the ability to edit on my own.
So please :)

Ah that's because to limit the amount of draw calls the GUI is only redrawn if the internal button events are triggered.
Might need to have a look at this and overhaul the mod a bit.
