Thanks for the feedback, FichteFoll
I have considered combining these plugins into one and may get around to it in the future. Right now it's not planned however.
I recall someone talking about a randomise command as well. I'm sure it would be a fun little experiment for users who can't pick a scheme so I'll add that to my list of things to do.
on_highlight preview is an awesome idea! While it's not possible in ST2, the quick_panel in ST3 will definitely support this feature. I'll try and push this out tonight after work. Check back in ~8hrs
I realised during testing that some themes will package colour schemes in a subfolder which won't get picked up by Schemr. For this reason I removed the requirement for package filenames to start with "Color Scheme - ". Now .tmTheme files will be detected wherever they are saved.
