Outlook express theme for Thunderbird 102 (work in progress)

I'm working on a css theme for thunderbird 102 that resembles multiple versions of OE, I'm not going for a 100% conversion or anything (I'm not even sure if it's possible), but I want to get it as close as I can + make thunderbird look better with the classic theme.

I wasn't sure where to add this, but I think the only external resources I used here was CustomJSforFX

MSFX Firefox + Thunderbird

Unfortunately the contacts pane is only cosmetic, there was an addon, but it doesn't work anymore

The tabs are currently hidden, I'm still experimenting

Message window

Compose window

I haven't figured how to change "Thunderbird" in the title bar
Also, the buttons on the right of CC aren't accurate, but I didn't want to cripple functionality

Main page + message filters

The main page is kind of lacking, I'm not sure if I'll do more work on it yet
Also, the spaces toolbar was modified to look like OE6's mail bar, but the functionality is more comparable to old versions of outlook

Address book

I'm not completely satisfied with it, I've had a lot of issues with thunderbird's web components

Calendar and tasks

I actually had to retake these the day after fixing issues with the mini calendar and the disabled menus in the event window

I actually didn't mean to post this on my birthday, I just procrastinated on this a lot in July
Also, I'm not sure what causes this but switching the calendar tabs causes issues with custom scripts updating

Chat

I'm not sure how the chat works, so this probably needs more work

System color testing

This shouldn't really be note worthy, but I had more issues than I'd like to admit

with OE5 resources

Since they're pretty similar I'm planning on making other variations including:
Microsoft Internet Mail and News, Microsoft Exchange, Outlook express 4, Outlook express 5, Outlook express 6, Windows Mail, and Windows live mail
