Okay trying to help you guys here so bare with me.

1st post today :
Hey guys,

How to :
[code]
In XML//XML64 => client.config2.xml
Change
<option name="train-complete-delay-time" value="1.500000" />
to
<option name="train-complete-delay-time" value="0.100000" />[/code]

This reduces the delay when changing skills blabla.

Addon patch file attached to the post.

Enjoy !

2nd post today :

Hey guys, let's try this without typing any code or how to this time.

This reduces skill change time. Enjoy !

Yet somehow I already posted it as comment once and it didn't do anything and still works on both threads :

https://www.bnsbuddy.com/index.php?threads/hard-to-explain-it-in-the-title.149/#post-530
https://www.bnsbuddy.com/index.php?threads/addons.17/#post-630

It seems more like I'm not allowed to either attach a file, a file containing a .patch file or it just doesn't like me.

Anyway if all hell doesn't work you can post it yourselves,

Place in a .patch :

FileName = xml[bit].dat.files\\client.config2.xml
Search = <option name="train-complete-delay-time" value="1.500000" />
Replace = <option name="train-complete-delay-time" value="0.100000" />
Description = Greatly shortens delay after skill change confirmation
