I've released a new version of otime here: https://github.com/ThisDrunkDane/otime/releases/tag/v0.6
or you can download it on HMN project page.
This update is just an update to the latest compiler release as of this time, and to use the new and improved fmt.odin from the standard libary. No more crazy long decimal numbers.
I've tried to work on markers but my efforts just resulted in completely broken program. So I'll have to try another approach.
This version shouldn't break with your current .otms
but I'll probably break compatibility in the next version.
