TFT (or any screen) that uses minimal memory (for text)

Using Arduino Displays
1

Hi everyone,
I was wondering if a screen (with a microcontroller) exists, that takes care of most computational/storage work. I have an Arduino Yún and my program storage space is full. I would still love to add a screen to my project though.
It would be cool if there was a screen you could just say,..
lcd.println("My text");
..multiple times and it keeps scrolling the text or whatever.
(Without tons of libraries,... like the adafruit tft which I have....)

#include <Adafruit_GFX.h>
#include <SPI.h>
#include <Wire.h>
#include <Adafruit_ILI9341.h>
#include <Adafruit_STMPE610.h>
Adafruit_STMPE610 ts = Adafruit_STMPE610(8);
Adafruit_ILI9341 tft = Adafruit_ILI9341(10, 11);

Does anyone have an idea?
Thanks a ton!
PS: I'm trying to cram everything in a box and I do have another Arduino Uno but I don't know if it'll all fit.....

I did find this one SmartGPU2 but I wonder if this would actually solve my problems...

Maybe another Arduino could solve the problem? Or a compatible device with lots of storage?
Is there a Wi-Fi Arduino compatible device? I also have the GSM module (i don't have to transfer a lot of data)...
