classic advisor = blue headers, 3 columns, does not show tech percentages
old advisor = blue headers, 3 columns, does show tech percentages
new advisor = red headers, 2 columns

As far as I can tell, changing the advisor style for the user only changes what you see on your country's advisor page. It doesn't change what you see when getting a spy op (which is always classic) or when viewing a saved spy op (which is always new). I would like to retire the classic and old advisors and make everything use the new advisor. The new advisor shows the most information and it renders correctly even when the country has large numbers for some fields.

I think it’s a good idea.

Old things go into retirement.

I prefer the 3 column layout but it's NBD.

I always used the old advisor :(

Oh well.

I also used old.....

I need also old, but I don't get it anymore....

i was used to old one, but it gone now

I will add this back some time this week.

My hero <3

Though, to play devils advocate, it was kind of forcing me to get used to the new one ;)

Change the new advisor to include what the old advisor has and then retire the old one

It's not the content, it's the location of everything that is different.

The old and classic had stuff in the same place, the new one moved stuff around it was a bit discombobulating.

However, the new advisor is better - format is nicer, layout is not as glitchy, handles big numbers etc.

I added back the classic and old advisor. The setting to change it has been moved to game preferences. However, please understand that spy ops will change to the new advisor style in the near future.
