Using Plover with other theories

Plover can load RTF/CRE dictionaries out of the box, but its support for the format has the following known quirks, which can usually be worked around using Plugins, which can be installed from the plugins manager:
 * No automatic reversing numbers: pressing the number bar together with these keys:, does create numbers, but adding   to the stroke doesn't automatically reverse the order of the digits.
 * Plover doesn't have built-in support for strokes retroactively changing the capitalization more than one word back. There is a plugin for that though: Plover retro text transform.
 * It also can't automatically format things like roman numerals, for that you'll need to install the Plover number format plugin.

Additionally, Plover's default orthography rules might differ from what a particular dictionary expects.
 * In the case of Phoenix, which expects fewer rules than Plover normally uses, you can use the Plover Phoenix Stenotype plugin, then open Plover's configuration window and choose the "Phoenix Stenotype" system in the System tab.
 * For other systems, there's Plover Minimal English Stenotype which removes all the rules and automatically-folding suffix keys.

Other languages
The old wiki has a list of chorded systems for various languages. Known issues that aren't mentioned there (yet) include:
 * The Danish system was made with an older version of Plover and had some issues even with that. Plover's current way of adding orthography rules might cause some trouble for that language, since multiple words with different meanings, parts of speech and pronunciation can end up having the same spelling. It should be fixable, but might take a while to do so.
 * The Especias system should work for Spanish but currently doesn't. As the developer of that system, I'm aware of it and hope to fix it some time in the first half of 2022.
