I suggest to move custom fields from tab up. I suggest to place them between the ‘standard’ fields (like status, due data, time estimate) and the task description. Alternatively, they could be displayed within the ‘standard’ fields which which be my ideal solution.

Reasoning: 100 % of time, I have open the tab. Moreover, I have just searched for 15 minutes how to show the custom fields in the task view, as I could not see them there.
