IDE 1.8.9 - any issues?

I hope the new IDE version will be good to you!

Alas, no. It mostly worked, then I saw when I opened a file that numeric literals, which had been yellow under the previous dark theme are now black. Likewise [],(), and {}, which had been an off-white. I've edited the theme file, now in the sketch folder, and pasted into the Arduino lib folder but no joy. I've been restarting the IDE figuring it loads things like themes only at startup but this has no effect.

Specifically, I altered these two color settings with no effect.

# TEXT - LITERALS

# constants & datatypes
editor.literal1.style = #006699,plain

# p5 built in variables: e.g. mouseX, width, pixels
editor.literal2.style = #F8F53B,plain
editor.variable.style = #F8F53B,plain

In the standard theme file they are: #00979C,plain.

So, first off, am I changing the correct values?

Edit: I just found this: GitHub - jeffThompson/DarkArduinoTheme: A dark theme for the Arduino IDE – no longer maintained :(

Seems there are some new wrinkles to navigate. >:(
