Remove the text tool reset by deleting the last letter
I don't know who had the bad idea of adding this feature in GIMP to go back to the font and standard size when deleting the last letter, but for the love of god, remove it, or at least add the possibility to disable it. This makes working with text in GIMP very difficult, I always forget that GIMP works like this (the only program I know that has this feature) and I end up deleting the last letter and having to define it again as I want my font.
Changing that should be simple for any novice developer.
