"Text editing is still plagued by poor user interfaces:
when you press the "A" key, the letter "A" appears on the screen without any interaction, when you press "Delete" it disappears in an instant,
the cursor disappears to the right edge of the screen, then suddenly appears on the left edge"
Maybe I'm old fashioned, but this is exactly what appeals to me regarding text based interfaces.
"Although Japanese is primarily written vertically, there are not many text editors that fully support vertical writing.
However, you can gain deeper insight by reading a text vertically or horizontally, or by flexibly changing the layout and rereading it.
With Sakishi, you can instantly switch between vertical and horizontal writing while editing a document."
That was my "aha!" moment when reading this. Japanese has been made to fit Western convention a lot of the time, but it's good to have another option.
Always remember who your target audience is. If it's people who actually use a computer for writing, instead of just looking at cat pictures on the internet, then they probably don't care about fancy transitions and animations. They want to get shit done and they need their workflow to be optimized.
If it's just for normal people, then go wild with all the useless, CPU-wasting frills. Feel proud about it, even. In 2024 a snappy user interface only requires a few GBs of RAM, several intercommunicating processes and the ENTIRE FREAKING WEB STACK.
