roadmap to first release, in no particular order {
finish implementing OSK! {
enable scrolling preview (and scroll to cursor where applicable)
polish!
- fix cursor-down
polish! {
- background
actual cursor image?
}
InputManager::OpenKeyboard
}
fix [ offset (-1 it)
add generic backdrop assets (and form)
fix lowercase j running into things
adjust monospace line height (and maybe offset) to closer match the vwf of the same size
add license!! (MIT?)
ADD README.MD PLS
} then consider these before 1.0 "gold" {
should form priority be a float?
- should form priority be a float?
make closing forms a bit less finicky (add them to a separate list and let the Application remove them from the list)
add customization for Button (alternate idle/press images, optional glyph drawable)
^ use that to spice up the OSK
