An option under Task properties to enable a timeout after x time so that tasks that get stuck due to actions without timeouts or whatever the reason. This will essentially end the task regardless of its status so other tasks that are Q'd up can proceed without incident. 

When third party plugins are involved, and even some native Tasker actions, often times errors will result in tasks never completing and end up stuck in an indefinite run state even when "Continue Task After Error" is selected. If the action doesn't throw an error, then it'll just keep trying to execute

Hello. Could you please make icons(scene-image/task icon) can use base64/svg<Scalable Vector Graphics>? It is very difficult to find a suitable icon for a task/scene.(And many people don't want to install other icon app.) The personal task icon will not be missing when it is shared.
