Player can review the number of seminar items left via "Inventory" tab in the "Player Information" menu. However, this information is usually way more beneficial to have access to while handing out the seminars. This is particularly true when training multiple crew members one after another.
To make this possible, the conversation options for handing out seminars should include the current number of seminars left in the inventory. This way the player can instantly make a decision on whether to promote the crew member and spend the last high-level seminar, or keep the seminar for some future use - all of this without having to spend time on "aborting" the training and opening up a different game menu.
For example:
- Seminar for 1-Star Crew (Piloting) - 8 left
- Seminar for 2-Star Crew (Management) - 2 left
