I don't notice the jittery-ness anymore (aside from town-lag) looks like 1.18 was a pretty giant leap towards a complete game... aside from the fact that they nerfed all the exp by WAYY too much, I thought of a few more tweaks that could add ease-improvements as well as a mount idea for better travel.
I wouldn't mind raising my own chocobo as long as I could call it whenever I wanted, (aside from during minor leve quests), they could rent you a chocobo pass that expires after x(2?) hours and when you unmounted your chocobo it would jus graze around the area you left it. Or you could have it so you can only unmount near fences?/someplace to tie your choco/trees etc.

As for UI improvements and other issues needed for 1.19:
-ability to walk away from npcs/stores/bazaars to cancel dialogue.
-the enter function doing more than just brining up your attack bar when you're highlighted on a friendly player... (bazaar/check?)
-a quicker way than /t <t> to talk to someone without the use of the keyboard..
-maybe add /trade /tell /invite /add friend under the bazaar/check area in the main menu
-multiple windows open at once from all menus... IE (gear and main menu) (bazaar & main menu) (etcetc)
-a 'create waypoint' button past the map button in the journal. (works only in the same zone)
-a way to log out/get booted/pc crash during a levequest and not fail the entire thing. (probably would take alot of work to implement this around the current levequest system)
-Minor issue: a right-click 'create waypoint' function on the main map?

all in all, keep up the good work.. next we need a way to alt-tab and not kill the game. Like when I'm running background processes and winrar pops up, I fail the levequest...
"Oh well you can run windowed-fullscreen..." yeah... at the cost of 20% reduced framerate... -.-; not everyone has supercomputers LoL

good looks cuz, keep up the pace n don't fail me now square-enix
