09 Jul 2023 - As of the 17th of July our emissary NPC Christopher Tibis will again have to return to his duties in the celestial realm. Be aware that the anniversary tokens will also fade away on that day at the time of the server save. Therefore, if you still haven't exchanged your tokens we suggest doing so as soon as possible.

Good choice but this makes it temporarly full screen. Borderless maximised is different. You can still (want to?) see the Windows taskbar. If you use ALT + ENTER, you will also get reset to the usual window size/position if you click somewhere else outside of it(e.g. 2nd/3rd+ monitor setup)
Afaik they could make the borderless client with an ingame option that only requires a restart, there are variables that enable or disable whether this control bar is shown in a program.
