If you haven't deleted the old script, you can simply search for an update using tampermonkey or violentmonkey. You'll have the latest version available.
As for the notification, structurally it is correct, you are the owner of that post, but semantically it is wrong because it is neither a quote nor a citation, I should match them as reference.
As promised, here is the feedback.
1. Found a thing called BRDb tracker, and upon setting it up it's giving me an error. Work in progress, maybe?
2. In compact mode "Quote" button is missing. I can only use the overall "Reply" button. As for non-compact mode, no issue there.
Compact Mode:

Non Compact Mode:
3. Trust page is accessable now. But what's with this multiple lines/mergins/paddings? Looks kinda messy!
4. The previously reported duplicate action buttons, or the UI is fixed now.
5. The Negative feedback always shows in
Red, but here it wasn't! You need to fix that. I'm referring to the trust page!
6. There is no white flash in your theme. Cool! How did you fix that?
1. One particular bug I wanna point out that I noticed with every other theme (including yours). When I'm in a darkish theme, there is a split second white flash, very tiny seconds. So, see if you can eliminate that. That flash is basically the original BTT theme before the CSS code loads.
about the flash i already trying to solved that few times, but i have to accpet that, this is just a scripts, browser may load this script slower few millisecond, that why flashing keep happens. even i tried to hide OG theme before the skins fully loaded, but it doesn't work as i want so far

So far this is all I got! Comparing with masulums' theme with yours, I find his to be much more cleaner btw.

Yes, it's still a work in progress but it works, you have to manually change the username within the userscript and save. I'm trying to find a way to do it automatically, but I haven't managed it yet. I'll do it later. The compact mode is not yet complete, I only made a few changes there. For the messy trusts I didn't see any differences, actually I didn't make any changes there, that's still the original Bitcointalk table just with my theme applied on top. As for your preferences, I don't know what to say. My projects can't please everyone, some like them and some don't, but I accept all feedback, especially those with more criticism.
