NBT Editor v1.13.0

Main Features:

NBT Autocomplete integration - when that mod is also installed, you will now get NBT suggestions, including tag names (use alt to navigate the dropdown in multi-line fields)
Color selector for custom colors, instead of just a hex input
Customizable command aliases (in /nbt config), with built in "extreme aliases" - one or two character aliases
Item size tooltip - shows the bytes/kb/mb/gb of an item (must be enabled in /nbt config)
Unbreakable itemfactory (/itemfactory unbreakable, /if ub)
Container support for chiseled bookshelves, suspicious sand & gravel, and decorated pots
Glowing signs color dropdown
Client chest pages can now be named
/clientchest now can take the page number or a page name as an argument
Page Up and Page Down keys now can be used to navigate the client chest, with Shift for jumping (use /nbt config to inverse the keys)
Made scrollbars better and added them to the multi-line text fields
Cancel option for the shortcuts and aliases config
The max scroll speed is now 10, and defaults to 5 (instead of a max of 2 with 1 default)
