tMORE saves the text that you enter in the editor as an embedded image in your tweet, allowing you to use many more than just 140 chars.
As tMORE saves your text as an image, you should know the guidelines from Twitter regarding Images.
From the Twitter Guidelines
Twitter gives users the ability to attach photos to any of their tweets. However, when you attach a photo to a tweet, Twitter needs to create a separate link for that photo, so ultimately you have fewer characters to work with. The photos that you upload are going to appear in the streams of your followers and the streams of their followers should your photo get retweeted. Photos that are included in public tweets may also appear in certain Twitter search results.
It’s also important to note that Twitter may collapse your photo into a smaller version to fit seamlessly in a user’s stream. In order to make sure that Twitter is displaying the portion of the photo you want followers to see, make sure the width of your image fits the minimum requirements and that your content is horizontally centered.
- Minimum to appear expanded 440 x 200 pixels.
- Maximum to appear expanded 1024 x 512 pixels.
- Appears in stream collapsed at 506 x 253 Pixels.
- Maximum file size of 5 MB for photos, and 3 MB for animated GIFs.
How is this effecting me in tMORE?
The whole editor area (as you see it on your screen) will be saved as an embedded picture to your tweet.
Those guidelines above are the reason why you can’t make the editor window tinier than 440×200 or larger than 1024×512 pixel. By default tMORE starts with an editor area that will be rendered to a 506×253 pixel dimensional image.
Those dimensions also are the reason why you don’t see any scroll bars for the editor.
