RPG Help please! i dont have a clue anymore

i want have 2 thing i want have in my rpg 3d games

1] Actionbar

currently i have action bar from DARKON FORGE from asset store (already removed) but the code is too complicated so i can only add custom icon, font but cant add skill function to the action bar and its java script so i really want easier actionbar skills that can drag and drop and have tooltips when we point our mouse to the icon for rpg and c# language and easy to modify, i already searching but didnt find anywhere, what i find its just darkon and UGUI ($35) only

2]

as you know in unity if you set the screen into 16:10,16:9, or full screen if i already set void gui, gui text, the text can moved , even we cant see the text based on which size the setting of our screen, i set my hero lvl on the screen by using gui text but after i set it to full screen my text is screwed so i want to know what kind of code is used for text like hero lvl so if i changed the screen size, its doesnt matter also i want add frame in the hero lvl like in other mmo the level is not just a number , but have frame and skin so its looks more cooler

for now thats the trouble i have ty for anyone can help me :) srry if my english is bad
