Training Queue - Sort By Training Time

That’s the purpose of the Player Features & Ideas forum.

This is not remotely related to your QoL request. I would estimate that only 1 +/- 1 players rage quit EVE over their inability to sort skills in the skill planner in the past year.

Indeed.

This is literally among the littlest and most insignificant and time-insensitive of requests that could possibly be made. CCP made an official Little things / Small QoL suggestions thread for precisely requests like these. Not-coincidentally, this thread appears in the Player Features & Ideas category.
