Living without a text expander might be possible, but is utterly pointless. I tried a lot of text block tools and think that Typedesk is among the best ones. Unfortunately my company uses PhraseExpress so I have to work around with both for the moment.

I guess there is still much room for improvements in Typedesk:
Having the possibility to add random strings is one feature I like a lot. This makes the outcome more individual.
I miss using the "+" for starting my text blocks instead of ":" or "/".
Integrating a translation function based on deepl for example would also be nice.
Tighter integration with Office365 or Gmail would also be nice so it could grab the names accordingly.

P.S.: A proper roadmap would give a bit more confidence in your business.
