 ## TODO
 Emulation:
+- ***Fix signal truncation issue!***
 - General code cleanup
 - Reverse track precompute & replay
+- Prefix/between/suffix addition to config menu
+- Parameter tuning, find best defaults, troubleshoot improperly parsed TX
 - Implement/integrate better bitmap than hacky first pass? Boilerplate from [antirez](https://github.com/antirez)'s better approach (from [ProtoView](https://github.com/antirez/protoview)) included at the bottom of `helpers/mag_helpers.c`
 - Should the main timing-sensitive section be branchless? (Remove `if` and `switch` statements from the `FURI_CRITICAL...` section of `mag_spoof()`?)
 - Pursue skunkworks TX improvement ideas listed below
 
 Scenes:
 - Finish emulation config scene (reverse track functionality; possibly expand settings list to include prefix/between/suffix options)
 - "Edit" scene (generalize "Add manually")
+- "Rename" scene (generalize input_name)
 
 File management:
 - Validation of card track data?
 - Parsing loaded files into human-readable fields (would we need to specify card type to decode correctly?)
 - Update Add Manually flow to reflect new file format (currently only sets Track 2)
 
 Known bugs:
+- ***From debug logging output, seems precomputed signal is getting truncated somehow! This is priority \#1 to fix***
 - Custom text input scene with expanded characterset (Add Manually) has odd behavior when navigating the keys near the numpad
 - Track 1 data typically starts with a `%` sign. Unless escaped, it won't be displayed when printed, as C considers it a special character. To confirm: how does this impact the emulation when iterating through the chars? Does it get played correctly?
-- Possible file format issues when Track 2 data exists but Track 1 is left empty; doesn't seem to load happily.
+- Possible file format issues when Track 2 data exists but Track 1 is left empty; doesn't seem to be setting the Track 2 field with anything (doesn't overwrite existing data). However, `flipper_format_read_string()` doesn't seem to return `false`. Is the bug in my code, or with `flipper_format`?
 - Attempting to play a track that doesn't have data results in a crash (as one might expect). Need to lock out users from selecting empty tracks in the config menu or do better error handling
