Text color/Share restriction feature/Add separator

1. Text Color

When I worked on this before, I wrote the text with different colors for the top and bottom dialogue. Using custom colors instead of the sample colors made color selection incredibly difficult. With hundreds of lines of dialogue, I had to meticulously move the mouse to the exact spot on the color palette for each line, and if I missed it slightly, I had to find it again... hundreds of times. Just having these two features would have made it much less tedious T_T

1-1. Recall Recently Used Colors

You know how PowerPoint or Hangul/Word usually show a recent history list so you can instantly pick the last color you used when applying text color? That kind of feature would be great. If remembering multiple colors is hard, at least let us save one color.

1-2. Specifying by color code

When specifying text colors in the color palette, I noticed the code appears below in the format #000000. Since clicking the color with the mouse was difficult, I tried to paste the code directly. But... I couldn't edit the code displayed on the color palette screen myself? I can see which point on the palette corresponds to which color code, but I can't paste the color code I actually want to retrieve that specific color. Honestly, I didn't expect it wouldn't be editable, so I thought it might be a bug and tried going in and out of the settings repeatedly... but it didn't work on other devices either😂. So, I think it would make the process much less tedious if we could at least manually input the color code to specify the color.

2. Sharing Restriction Feature

Simply put, I'd love to see a private post feature added. Currently, anyone can click a shared link and access it without restriction. Adding a password feature would require entering a password upon clicking the link to view the post. This would be useful when I want to share a post only with specific people.

3. Inserting Divider Lines

It would be great to insert dividers into posts within the editor. This would be useful when writing long posts with frequent scene changes, inserting typography for section titles, or adding postscripts or author's notes at the end. It's a feature commonly found in other editors but currently missing in Novella. Since it's a basic function, it feels a bit disappointing.

Thank you for your continued hard work. I hope you'll positively consider adding these three features. At the very least, please add #1 and #3!
