 # Roadmap
 
 - Complete translation English and Spanish
-- Security (API 1)
+- Somewhat more security in API 1
 - Stabilize all
-- If anyone wants to create a better gui in Python it will be awesome. I used easygui to create a fast usable gui but maybe is not very proffesional.. Anyone? 
-	I had some in TKInter but easygui was very useful without making difficult release it as first usable version
+- I created a simple GUI in EasyGUI to be easy used, but maybe I will transition to a web GUI more dynamic and visually better
