First release 1.0.0
This is the first release of the app :D
There are a few bugs, like editing the search term (in the find window via CTRL+F or CTRL+SHIFT+F) while a search is running; the items won't get cleared. Currently working on fixing that, but all you have to do to clear it is clear your search terms and the type them in again (or cancel then type a char quickly then backspace)
When you navigate to a tag compound/list with a large amount of items, the app may freeze for a sec while it loads item on the right list (because virtualization isn't working on the list for some reason but it works on the tree...)
A few shortcuts don't work (e.g. f2.ctrl+r to rename) because I haven't yet figured out how to send shortcut events to objects in a way that doesn't involve adding/removing event handlers per-object. Will fix soon
Region files cannot be saved yet; only previewed. But .DAT files can be saved, however, i wrote the NBT classes myself from the forge 1.6.4 environment I have setup, and even though I've checked it a lot, there may be some bugs still that corrupt the NBT data when saved (from my tests though, it never happens). So make sure to keep backups just in case
Apart from all that, it works quite well. To search for items, you can select an item and do CTRL + F to search in that specific item, or CTRL + SHIFT + F to do a global search (across every root item). You can double click the items in the result list to navigate to them. Right clicking items shows a context menu of things you can do (e.g. edit, remove, copy, etc). Double clicking most items will open the editor window, and double clicking compounds/lists will navigate into them like a file explorer
