CheckMenu para Mac

Nice free app but functionality is limited at present. A floating window would be useful, as would hotkeys to invoke it and to create a new task. Grouping tasks under category headings and/or colour-coding would help clarity, as would optional coloured menu bar item (eg if tasks remain outstanding). To really make it useful, setting the task list to pop up or the menu item to flash at a given time (eg 1 hr before end of work day) would be great for those of us who forever write lists and then forget to look at them. I'm not looking for a full-features planner reminder app, nor a replacement for Reminders, but I think this great - free - start could add a lot of value while still remaining simple. - come to think of it, is there a way to ingrate Reminders to optionally display those in the app?
