i think there should be slight improvements in chess.com tactics trainer

this is especially for staff members i have a suggestion for the tactics trainer. i noticed that in some puzzles there are alternate variations and if i do the second variation the answer would be the first variation so, what i want to convey is that you can use an alternate correct move like for example 'alternate correct move please keep looking for another move'. you can do like that. i got the idea from chesstempo.com. i told this because i want chess.com's tactics trainer also to be equally good. even non-staff members can have their say. thank you
