Changelog

Features

Added context menu; includes Undo/Redo, Center View/Fit, Zoom In/Out (only able when Pan tool is used).
"Not allowed" mouse cursor will be displayed if no frame is selected.
Tooltips will now contextually show if tool use would be invalid.

Replaced relevant Input widgets with Drag widgets (with custom wrappers for snapshot functionality, etc.)
This means you can just drag stuff with the mouse to change the value, rather than having to manually input things.
Cleaned up the bottom buttons a bit.
When multiselecting, options will be disabled unless you check something

Redesigned to look more similar to Spritesheets, with icons.
Can now double-click to open file directory, like Spritesheets.
Added "Reload" and "Replace", similar to Spritesheets.
Updated context menu to include below options and Undo/Redo.
In default settings, should be tabbed with Spritesheets (they're like external resources, y'know? makes sense)

(Sorry about this, but removed Item multi-select. It's a headache and the implementation was god-awful and didn't work half the time).
Updated context menu to include below options, and Undo/Redo.
Added context menu in item child; includes below options and Undo/Redo.
Fit Animation Length now can use the "Fit" shortcut.

Reimplemented "Change All Frame Properties" window. Useless, with the multi-select window? Yes! But faithful? Also yes!

(!!) Fixed issues with UTF-16 filepath handling (settings, loading anm2s/sounds/spritesheets, etc.). This should allow non-ASCII/English characters more easily!
Changed the format of sounds to match Spritesheets
Fixed crash where the Timeline window dereferencing a pointer that was null in some cases. This issue was actually what made prior versions' settings file "backwards incompatible"; this has been resolved. Sorry for my schizophrenia.
Fixed issue in Timeline where layer animations/items were rendered in reverse order.
Fixed issue where default UI scale setting would erroneously print a warning in some cases
Fixed issue with "None" being unlocalized in the case of Sounds.
Fixed issue with dragging to change the duration of Root frames.
Fixed issue with sounds not being preserved across changes in snapshots (undo/redo)
Many instances of pasting things did not update snapshots; this has been fixed
Removed selection box in some cases of multiselecting (more trouble than it's worth).
When pasting frames, animation length will no longer be set automatically to the current length.
When running the program with default settings (i.e., for the first time), window will scale automatically to display size.
Fixed Render Animation "To Selected Frames" not really being accurate
Fixed an issue where the Color Picker tool would return #FFFFFF00 instead of #0000000 in transparent areas
Fixed issue with opening file directories in some cases.
