Today It will only show the tags available when you type the first letter or the keyword and my request is if its possible to include a list the all tags we have already use and mark them - like a check box without the necessity to write the first letter.
Welcome to the community! Thank you for sharing your feature request with us. I understand that you would like to see a list of all the tags that have been used and have the option to easily select them without having to type the first letter. This would certainly be a useful addition for many users.
We have added this to our product backlog for consideration in future updates to our software.
If you have any other suggestions or feedback, please don’t hesitate to let us know. We are always looking for ways to improve our software and provide the best possible experience for our users.
