Youre welcome, good luck :D

There’s a software called Winboat which integrates Windows apps natively in your Linux system and under the hood it’s spin up a virtual machine for it. You can try that for Excel

You can use Ventoy to have many ISOs on one stick ^^

Switch to Anilist ^^ Many FOSS Apps available :)

Switching is super easy

Focalboard is a good alternative Sadly it doesn’t seem to be maintained at the moment.

For Personal To-Do List & Habit Tracker I use Habitica it’s pretty cool :)
