In this latest version 1.3 of the XPTweak plugin, an option has been implemented allowing server owners to decide how many XP points will be distributed in the defined orbs during the XP shower.

v1.2 #ChangeLog
Partial Inventory Storage ( /xpt inv): Smart storage that fills your available inventory slots with XP bottles and keeps the remaining experience in your bar, preventing inventory overflow issues.
Real-Time Rain Timer ( /xpt time ): Added a precise countdown clock showing exactly how long until the next XP Rain in a clean `00h:00m:00s` format.
XP Inspection ( /xpt inspect <player> ): New auditing tool that allows checking any player's exact level and total experience points.
Enhanced Rain Announcements : You can now configure a custom location-instruction (like /warp xp) in the config, which will be automatically included in both In-game and Discord announcements.
Localized Time Units : All time-related messages (hours, minutes, seconds) are now fully translatable across all 4 supported languages.
Stability & Safety : Improved command argument handling and added internal task cleanup to prevent duplicate messages during reloads.
Bug Fix - Duplicate Announcements: Fixed a critical issue where rain announcements were sent multiple times. Integrated a unique task ID system and improved scheduler cleanup during reloads to ensure clean messaging.

Fixed /xpt all command giving all player experience in bottles to inventory full!

Old situation, rest of xp lose.
New situation
- payer receive warn about inventory
- if player decide accept, it rest of bottles dropped on the ground.

Optimization:

Moved Help /xpt [command] from config to both 4 language message files.
Added /xptc command on help list.
Recommed give that permission for players create custom unique bottle xp.
