You can only highlight everything using the alt attribute.

The creature icons have been fixed; now the portraits are like in the fifth game, which is much better.

Yes. Now, you just need to remember what the upgrades look like so you don't have to check every time which ones the main character has, so you can buy exactly the ones you need in the Castle, because the selected upgrade is always reset, and you have to choose the right one again each time using the arrows. And if there are several Castles, then... And yes, I also noticed a bug for the Necromancer. In the window for buying dogs, the upgrades are mixed up. That is, you choose the red ones, buy them, and you get the green ones, and vice versa.

A caravan would be useful. But at least the units don't disappear in the dwellings. On the other hand, such hordes appear there after a couple of months. I had the same growth rate for vampires and Knights, +9.

They also added a new template for maps. I launched it, and it seems to look good in terms of load. Now, they just need to fix the L key and a lot of other things.
In general, the first review on Steam quite clearly describes the pros and cons of the game. although I wouldn't agree with one point, but I've already forgotten which one.
