Some improvement ideas

First of all thank you for updating this amazing app, it really helps a lot for us to add easier new assets to our projects.
I would like to list some features I would love to see next !

**- An option to duplicate multiple selected items (currently you can select let's say 10 items, but it will only duplicate the first one)

• A dark theme Asset Editor (When I spend more than 30 min my eyes start to hurt because the app is so bright ! )
• A fix when you duplicate an item the app sends you to the first ID item, it should be like when you click on duplicate you stay on the ID you duplicated or the next ID created (duplicated one) instead of bringing the User to the first ID.
• When you change the sprite and click save, you have to scroll in order to see the item image updated (it should update the sprite image when clicking the save button, but somehow it doesn't work and you have to scroll up/down to update it)**
• Also implement adding a 96x96 sprites!

For me that's the features/fixes, other than that it's perfect and I really appreciate the effort you're putting into !
Thanks in advance

• When you click on open sprite manager the tab automatically hide, i guess it should work like you click Open Sprite Manager and the tab keep on the screen instead of hiding
