Calendars? How about Character Selection, too

Syp recently posted about the awesome in-game calendar that World of Warcraft has, and he wondered why more games didn’t have that exact thing – I agree. It would make planning and looking at events SO MUCH EASIER especially in games like BDO where there are always a billion events at any one time.
Then I thought for a bit and came up with my own “why doesn’t every game have this feature” feature.
The BDO character selection screen. ESPECIALLY if your game has multiple servers. Why can I not see my characters in World of Warcraft until I log in to that server. My memory is horrible, I have no idea which of my characters is where (as noted by the screenshot below).
In BDO you can see a list of your characters, their level, even their inventory, and you can swap servers or swap to those characters. I would love to see this implemented in other games (EQ, looking at you). Even the EQ2 method where everyone is listed at the main UI along with the server under would be a better method, then I could at least visually see where my characters are and potentially what they were up to last. As it is now, I have to keep a spreadsheet on who I have where.
There are some great QoL ideas floating around out there and especially for games that may not have aged well, it would be great to see these old interfaces uplifted and renewed for gamers today.
