[FR] Built-in Spreadsheet Viewer and Editor

[glufy100]

Description

It would be very useful to have an Excel-style spreadsheet feature directly integrated into the app. I manage many spreadsheets, and it's becoming difficult to keep track of them all. Having the ability to view, edit, and organize them within the app would greatly improve my workflow and productivity.

Impact

This feature would benefit users who frequently work with multiple spreadsheets, such as project managers, analysts, engineers, or anyone managing structured data. It would reduce file clutter, improve organization, and streamline daily operations by centralizing spreadsheet access within the app.

Additional Context

It would be ideal if the feature supports basic Excel functions (formulas, filtering, sorting) and works with both .xlsx and .csv files. Optional cloud syncing or tagging could further enhance usability.
