Hey there! I see the feature request/issue you created regarding the .drawio file extension compatibility, thanks for taking the time to do that! It looks like there’s some related conversation and context in this issue as well (draw.io and Flowcharting mentioned towards the most recent comments). Feel free to share any thoughts you have there as well!
No problem! I think the issue will remain until the .drawio file extension is supported by the plugin provider. I recommend keeping an eye on the issue you opened for any updates as they are available.
