No, we respect her sacrifice for the country and she was undoubtely a remarkable person (she's a saint, literally), her young death was a nation wide tragedy.
The problem is that this sacrifice - marriage with much older Jogalia meant that she basically gave up any real power - and it was after two years of her rule... when she was 12.
Technically she and her husband were equal, as Poland became diarchy for a bit - but it didn't work that way, she was an advisor and a first lady for the real ruler, Władysław II Jagiełło.
Keep in mind that in 1387 she was 13 years old.
EDIT
No idea. But note that the main point of this paragraph was the union of Poland and Lithuania - it was indeed a turning point in our history, but was it really her accomplishment? She was a child, it was the nobility doing all the planning, negotiations etc. According to XV century chronicler Jan Długosz, when she learned that she won't marry Wilhelm Habsburg she tried to hack trough the door with a hatchet, although that might be him colouring things up a bit.
I think the grand duke of lithuania, Jogalia (later Władysław II Jagiełło) was much more involved in shaping this union, he was also the peron actually ruling after marrying Jadwiga, I think most of Jadwiga's achievements could be also credited to him, as they shared the throne, and he outlived her byover three decades, after her death beating the Teutonic Order in the largest battle of the medieval era and starting the Jagiellonian dynasty ruling Poland for the next 200 years, among other things.
