Thanks mouser. I can't think of any minor changes though. If anything I feel like most other programs should adapt the minimize to tray icon and preview/checkbox options of the program.
Everything about the program seems major. If there's one major minor thing I hoped you'll consider for this version before the next major rewrite is that maybe you can consider the idea of creating one or two backup everytime a new entry is added because right now, it's just too easy to click on the wrong tree for saving and by then, having a backup of a deleted tree is kinda futile.
This is also a bit useless but I just like having lite versions of even lite programs. It's my personal thing though because I don't use it as what it's meant to be used but as an outliner. I'd like the variable to be replaced by a mini-tree again so while you can't highlight the text, you can theoretically cut it to even small parts and maybe the option to go to that part like a bookmark for the notes. I'm thinking since it's just based on the larger tree, it will be just minor to remove the variable option and replace it with a smaller tree within the tree. It's just my totally un-educated guess though and it's really just a minor musing of someone who doesn't know how to program as proven with this minor change which is more preference: Maybe you can have it set so the UI can entirely be hidden in replacement of a small +/-/E on either the right or left side of the screen and the configuration be set to the hotkey to ctrl+p. Again, these are just distractions to the true desires I've read many want out of this program though so it's not really a priority and I do mean it when I can't think of minor things that can be changed at this point.
(+ being add new tree, - delete, E - edit configuration)
