As a side-note: I created this plugin mainly to have the text wait on Commands/loops, and there is always at least 1 frame of delay due to this when encountering \CMD[].
If you don’t want or don’t need to wait for the Commands to complete, like when setting variables or switched or starting a parallel process, then Hakuen Studio Message Actions for RPG Maker MV MZ may be a less expensive alternative.
(Its base price is free, but please donate there if it turns out useful to you, if you can. I had a quick look after publishing this one and it’s very well-made.)
