I am still new to Sylestia but I have a few suggestions, some would be improvements and just something fun I thought of.

1 - It would be amazing if we could rename stable tabs, even inventory ones too. For my stable I keep my tanks in tab one, physical dps in tab 2 and my magic users in tab 3...in the future I plan to get a fourth tab or another stable for my pets I use strictly for missions. It would be great if I could label them, would look nice too!

2 - It would be really cool if we hovered over our animals in the stable and got a pop up with their sex and stats so we don't have to click on them each time.

3 - I think it would be super cool if we could party with other people, like 3 people per party and we each get to pick one pet and fight together...kind of like MMO dungeons.

4 - Oh, I would also love to be able to subscribe to theads so that I get a message when they are replied to, even ones I never posted in but just want to watch...I try to keep bookmarks of the threads I like but that just gets messy...having a subscribe button on each thread would be great.

Those are just some things I have been thinking about, if I think of more I will add them.

As much as I would like Tab naming, I doubt names would be able to fit since by the time you reach, say, 5 or so tabs there's barely enough room to fit the "Tab #" text in the small space.
Being able to name Stables would seem more plausible, though.
