Bunch of feature requests

[comesuccingfuccsloot]

hola. am trying out runmath for the first time. seems to suit my needs pretty well.

i do have some feature/improvement ideas if you're interested. i cba to make a separate issue for each one of them, so hope you don't mind the following list:

• Color input should have a text field too, to see and/or set the exact color you want
• Colors should support alpha, for a translucent app
• There should be an option to also set to foreground (text) color
  • Currently if the background color is set to black, the app is pretty much unusable, because the text is also black
• There should be an option to change the border color
• There should be an option to remove the border completely
• There should be an option to change the shadow properties, or at least toggle it off completely
• There should be an option for border-radius
• The settings window should be resizable
• There should be an option to hide the main app after clicking away from it (hide on focusout)
• There should be an option to set the font of the main app
• There should be an option to hide the help-text transitions
• There should be an option to set the padding (and maybe line-height) of the main app
• The keybindings should be configurable
• Perhaps being able to configure the in/out transitions might be nice too

i think that's about everything that comes to mind after a quick testing. cheers
