There are other methods if you just want speed including the Immersive Interactions quick gather option which is a one handed ani. I liked the look of these though just wanted them to be faster so I made this.
See the video for comparison.
Requires the original mod still
If you have Immersive Interactions just disable the plant gathering option in the MCM so its not overwriting.
Let me know if anything is wrong or if you think another animation needs more/less speed boost.
