［Feature Requests］Filter function and length sorting

[kkhkl]

Hello, I hope to add text content filtering, similar to the find dialog box. Only the content that meets the corresponding conditions will be displayed and edited. I used to have this function in EmEditor, but it is not free and I need to pay a high fee to maintain it after the trial period. It will be particularly important when dealing with some more complex text statements and regular syntax cannot be effective. In addition, text sorting currently does not support length sorting, which will also be useful when dealing with some classifications by byte length. I like Notepad 3 very much, and I hope it can be more perfect. If these two functions can be realized, I will be very grateful for your help. Thank you and good luck!
