Problem arise with Spanish...!!!!
The layout could be slightly changed and would help a lot.
I strongly doubt that Textware Solutions will change the layout. Over the years there have been some discussions about this subject in the regular Fitaly Forum
I don't know much about Spanish, but even for the quite fitting German I customized my FitalyStamp with custom slides for easier umlauts or frequent letter combinations. This might be the way to go for Spanish too.
