Transparent Tabs

Hi There

OK so 2 things, Thanks for a great piece of software, it's the best 12 bucks I have ever spent on the computer and saved me having a mental issue due to the standard W11 menu  

OK jokes aside, everything works great but I would like a few things sorted if you can.

1: How can I make the tabs transparent like the rest of the icons (See the attached images)

See the File Handlers group has transparent Backgrounds on the icons

and Net Stuff/New tab is almost completely 100% opaque

2: Here you can see I have chosen the ''File Handlers Group'' and you can see the transparency option is greyed out

3: Here you can see I have chosen the ''New Tab'' and set it to yellow and transparency to 10% but it's still nearly 100% opaque

If I set it to black it's better but still not transparent like all the other Icons

I have tried using the Garbage Bin icon to delete the colour but all it does is remove the yellow tint not the solid grey tab colour at all, the grey is still nearly 100% opaque

Hope there's a solution for this.

Cheers
