Hello @userBl3AStvH6H ,
Thank you very much for your suggestion. Your suggestion has been communicated to the developer and the development project manager is reviewing the content. After reviewing your suggestions, we will apply them to the official version if your proposal matches our concept. We appreciate your contribution to the beta program.
If you are ok to use good lock as suggested @SuperOvni , it would quicker. but would only apply 1 bubble color. There is no option to differentiate bubble color based on sender receiver or change for each conversation
