1.) Minute based merchants [Gold Club feature]
Not much to be said here, just adding a column to set minutes as well, rather than hour only. This would drastically improve resource moving with more precise crop shipments being available. The feature should be an exclusive for Gold Club users, as setting trade routes to go 3x would become obsolete in this case.
2.) Allies handheld for speed 5/10/15%
Don't you just hate it when you're trying to send troops to an allied member and they're always just a bit late? How about a handheld which would give speed bonus to your troops among alliance which you have a confederacy with? The item would give relatively low percentage, such as Tier 1 is 5%, Tier 2 is 10% and Tier 3 is 15%, so it's not overpowered-ish.
3.) Double-click the barracks/stable icon for GB/GS [Gold Club feature]
What some were complaining about could easily be simplified by just pressing the Barracks/Stable icon again to open GB/GS, provided you have them. Obviously a gold club feature as regular icons require that already. (or only plus, correct me if I'm wrong)
4.) Bonuses aren't temporary disabled while switching to an alliance you have a confederacy with.
Now this one is quite a pain in the a....nkle. You're planning to switch between wings to utilize handhelds such as Standard in important defensive situations, but once you switch to the other alliance/wing you lose Metallurgy, which is noticeable at higher levels and potentially have troops starving, due to Merchants reverting back to their default capacity.
(This would only work with alliances which you have a confederacy with.)
5.) Sitter special permissions
In very rare cases you're not available when needed and you see your artifact might get stolen soon, but there is nobody around with catapults to reach in time. So the idea is to grant your sitter a special ability to be able to use gold to demolish the treasury. Or in another case that you haven't got a spare treasury on your account, but the person you're sitting nearby has and you have to move an artifact. The function to use full attack to conquer artifact would only be possible if the person sitting would send the attack on his artifact villa.
(The function might feel a bit scary, but then again your sitter can just wall your army by sending smaller waves of troops raiding highly defended places.)
