Supermium

[Dave-H]

Glad you like Supermium, I've been using it for ages now on XP, and it's become my standard browser even on Windows 10.

To answer your questions -

1. Unfortunately, Supermium has no internal mechanism to set itself as the default browser on XP.
    It can be done with a lot of tedious registry editing, or by using a utility like PortableRegistrator.

2. This one is easy!
    Just type chrome://flags/#custom-ntp into the address bar, enable it, and fill in the URL that you want your new tabs to display.
    Restart the browser and there you are!

3. All I can suggest for that is to try different themes. Hopefully one of them will make things more readable for you.
    I'm sure that almost everything can probably be customised if you know how, but I don't have that level of knowledge of Chromium customisation I'm afraid.

Cheers, Dave.

#2 is done.  By setting new tab pages to Luxxle this largely covers for the fact that SM allows default search engines only if chosen from a small list.

#3 remains frustrating:  I cannot be the only one using SM with less than perfect vision and as far as I can tell all themes and color scheme customizations give fine gray lines and white icons on a very light background.  There may be worse scemes for visibility but it's hard to think what they'd be.   However I expect that as SM becomes more popular this will get fixed.  Windows and virtually all of the popular Win brwosers over the years had this right: SM (or Chromium's?) new bad idea won't go without an option indefinitely. 

Unless, of course, I'm still missing something obvious.  That could happen.

#1 The software you suggest is Win 7 and later I believe.  My 'modern' machine (this one) is XP.   I can probably do the edits by hand but I'll wait until I'm sure everything is stable.   Though come to think of it most other browsers are capable of setting themselves as the default so switching away from SM should be easy if ever needed.  

Supermium is tops.  

Thanks for the help!  Back to working on Win 98 on a Dell 4600.

PortableRegistrator 1.5 certainly works with XP, I don't know about any later versions.
I can upload it for you if you can't get a version which works.

FWIW I use the Classic Blue theme, which always looks very pleasing to me, but it may not help with your issue of course.
