Allow monsters that are physically able to equip items to equip them

One of the biggest perks of playing digitally is having everything at your fingertips. However there is a glaring error. If I as a DM want to give a monster appropriate magic items it’s a lot of side work when a simple equipment feature would streamline this. Say you have a mind flayer and you want to give it a mind blade, an example output would be once equipped it would populate as an attack option on the sheet to continue the perk of fast reference play. 

I don't think it's that much work to use the homebrew tools to make a variant with the appropriate new ability, even though they're clunky AF.

One problem with trying to do it by adding equipment is that equipment is made for players, and monster attacks are usually better, or at least different, than what the player gets out of it. They usually have more damage dice, and often special abilities, that a character doesn't get from the item.

(It's also a lot more complicated from a developer perspective. It'd be better, and likely no more work, for them to make it easier to customize monsters.)

Yes Monsters are more powerful but I find it silly to not give something like  a lich magic items. Yes it makes the fight harder but it’s realistic something like a lich would have items to augment their power even more. Not every fight should feel balanced but every fight should be winnable unless the story your telling is the heroes die heroically (which can be rewarding) 

or Even something less spicy; say you want to equip kobolds with some of new partner content for kobolds that is fun and flavorful but the only way to do it is to make actual pc and treat as a npc with is already gonna be stronger than intended

You can do all that by giving the monster new abilities in the homebrew tools. It's a much more straightforward way of doing it (or would be if the tools were less clunky), and means you aren't limited to just what the equipment gives a player.
