Tmoting is a great thing, once you get used to it. They do however have some limits and aspects that are, perhaps needlessly, hard to use.
Here are a few things I suggest to make them more intuitive:
1. It is currently impossible to start an emote with a comma in a correct fashion. This is relevant when you use prepending in order to construct things like:
"Just before the wave reaches Iocun, he takes a deep breath and dives below the surface."
If you try to achieve this with the command "em , he takes a deep breath and dives below the surface ++ just before the wave reaches", it will add a space between "Iocun" and the comma. I therefore suggest that whenever a comma comes at the start of an emote, the space between the emoter's name and the comma is removed, like it already happens for apostrophes (e.g. "em 's ears twitch slightly").
2. It is also currently impossible to use the extended functionalities of tmoting in the prepended part of a tmote. You can't thus make a tmote like "Casting a last glance at Sarapis, Iocun turns to leave", because Achaea won't allow the use of "$sarapis" in the prepended part of the emote. I believe this should be changed as well.
3. Last, but certainly not least, the whole syntax of prepending is very counter-intuitive. Achaea requires you to put the thing that will appear first in a tmote/emote as the very last thing with the ++ syntax. This makes it rather uncomfortable to write up emotes with prepended parts on the fly. I made a script to change this to allow writing emotes/tmotes in a different fashion, like: "em In a few quick strides Iocun crosses the room.". The script then searches the whole string for any appearance of my own name, and if there is one (like in this example), it will change the string to Achaea's syntax: "em crosses the room ++ in a few quick strides ".
I suggest that this should become the default way of prepending in Achaea: Search any emote/tmote texts for appearances of the user's name. If there are none, just emote normally with the name in front. If there are appearances, emote the whole thing as written, without adding the user's name in front. This would allow for a very easy and intuitive way of prepending.
