I posted most of this in the Forum instead of here, so this might be a duplicate.
Suggestion for the LEARN tab -> Faction mechanics videos: the videos appear straight over the post and it's hard to see where their limits are.
It'd pay off to have a slight overlay and make the video box modal.
Also, when a "press any key" button is on screen, this should be a mouse clickable button
Paint schemes: when selecting CUSTOM (nothing in the list, normal) then selecting ALL there is still nothing in the list. The contents of HISTORIC should appear combined with the CUSTOM (and maybe PREFERRED?) contents.
Paint schemes: when selecting a different type of unit, the animation is very laggy: click, there is an immediate zoom out with sometimes a change of unit, wait for two seconds then animation then zoom out (if it was not done before already) then new units appears (if it was not done already).
Simply remove that useless animation + zoom out and simply change the units on the fly
Paint schemes: there should be an option to import customs insignia.
Paint schemes: units seems to be merging into each other (ex Ork boys) when zoomed in (clipping)
Paint schemes: design of the saw axe of the ork nobz: why putting a blade protection? it's supposed to be an offensive weapon!
Elites: Elite detail screen (where you can change the doctrines): the clickable icon at the bottom for the mastery skin is not greyed and is clickable even if the unit has not reach the required level
Elites: while clicking on the detail of a passive ability sometimes a video appears (without a darker overlay which could be helpful), sometimes not. The "video available" icon is not displayed like it is in the LEARN section.
Multiplayer quick match screen: when clicking on a Elite / upgrade black box: clicking anywhere else or selecting a value will not make the hover selection disappear. Then only way to do so is to click on the race / paint drop down list.
