I regularly use three features in insert option of Xodo (android version)
1. Attach file – The file icon looks unattractive, in my opinion.
2. Link insert - There is no icon here. It opens up as expandable square. It would be better if it was an icon rather than expandable square /rectangle.
3. Voice insert option. I can only insert voice I record at the time and not pre-recorded thing. Can we somehow insert pre recorded audio files.
In icon customisation I can suggest that, icons like these are much attractive and aesthetic looking.
