Hello. I have an inline task in Tempo - it has Approval ability. Is there a way

The documentation for the Inline Approval feature shows that the only available option is Approval not Rejection forum.appian.com/.../Configuring_the_User_Input_Task

Normally when a task has to be rejected the person in charge of it should provide a reason, you could still handle this as a normal task and not inline approval so you can properly capture the rejection.

You should also start looking at the new SAIL Forms from Appian 7.4 forum.appian.com/.../SAIL_Recipes

In this case my Users do not have to enter a rejection reason. Once they click reject, the process calls a sub-process that contains an email with the rejection reason. My Users do not want to open the task in Tempo to reject it. If the inline task had functionality that included Approve and Reject, the process would flow normally. Please consider adding this capability to the inline task, this would save my Users so much time.

Are there any future plans to include a Rejection feature on the inline task?

The SAIL documentation that you referred is for regular task forms.

The reference number for the "Inline Rejection" Enhancement Request is AN-53387. You can review the release notes of a future version to determine whether the feature is available.

For now the end-users will have to open and reject.

Are there any future plans to allow BOLD font or Font Color in the Task Display Name? This would be very helpful to my users, giving them the ability to quickly recognize certain types of inline tasks in Tempo

Appian is continuously improving not only styling capabilities but also core functionality that will leverage more and more options. Take a few minutes to review the release notes of new versions (when they become available) to learn more about what new features are available. For a deeper view and on the features to come and much more I suggest you attend to Appian World www.appianworld.com
