Ideas and subtle changes

[wyvar]

Hi, I used xplorer for a while and i love your project!
Sorry for Sugestions, if they are offensive in any way - i hope they are not tho.

------ Animation and style -------

1. Settings animation.
   I feel like even if the animation is smooth, it lacks ... speed? It looks nice but for me it is a little irritaitng how long it takes. Maybe Speed slider, would be a good idea?

2. I feel like buttons of closing, minimizing and maximizing were a little too big. it tooks almost same height as the logo..

------ Functions -----

1. Sidebar - adding custom directories.
   Pinning TO the sidebar is simple, but i feel like it would be nice to add custom categories. where i can group and add custom icon to it (as configuration) or chose representing emote.

2. space as a quick bigger preview.
   I love the idea of - hover the mouse on the file quick smal preview. But for me it is too small - big prievew would be a nice addition. Sometimes adding old features from others are worth it

3. Field of directory, being empty - after clicking enter sending you to the error.
   The information of bad path is good, but clearing the view is not so nice.

Once again Great project and i want to see end of it!
