NBT Tooltip
I don't know my version or loader
A little map dev/mod dev utility to help people working with nbt items and tiles.
To see an Item NBT tag just activate the advanced tooltips by pressing F3+H, the tag will appear inside the tooltip. Longer tags will be presented in an auto scrolling view, the scroll speed can be controlled with SHIFT, to pause scrolling, and ALT, to speed it up. The default scrolling speed and the maximum number of tag lines shown at once can be configured.
More toggling options are available in the config menu.
Keybinds to copy the NBT tag to your system clipboard are configurable in the "controls" settings.
Multiple presentation formats are available both for tooltips (default: custom human readable and color coded format) and for copying (default: json), all configurable.
Using ModMenu to edit configuration files is highly suggested.
