 While the conducted studies provide strong evidence that supports the usefulness and intuitiveness of built-in discrete time in spreadsheets, several important questions remain open for future research. One of the key next steps is to evaluate whether ABM Sheets can be used by users with no technical backgrounds. Although the system was designed as a minimal extension to the conventional spreadsheet paradigm, further validation of its accessibility for non-technical users is still needed. Conducting a dedicated user study involving such participants would help verify this assumption and further improve the usability of the system.
 
 Another area for further improvement concerns the design of temporal cell references within the system. During the evaluation study, some participants naturally leaned toward using explicit functions such as `PREV` for referencing past values, even though ABM Sheets currently supports a simplified syntax. This raises an important question about how to best represent self-references accessing previous time steps in order to ensure clarity and consistency without sacrificing usability. Future iterations of ABM Sheets will explore these alternatives in more depth, aiming to identify the most intuitive approach for users across different levels of expertise.

+During the user studies, the system captured user interactions and usage of ABM Sheets and saved the logs to the database. As an example, logs from two of the study participants can be found in [this folder](/logs) both in `.csv` and `.json` formats.
