Mainly for personal use, but I thought I'd share it since I had little luck finding good alternatives online. Currently only supports 0x0.
Requires fzf, xclip, bash, some terminal (YMMV), mpv for fzfplay.sh
Adjust paths in the fzf scripts to your liking.
Bind (for instance, in xfce4-keyboard-settings) single-use scripts (clip.sh, uploadfile.sh, uploadimage.sh, uploadtext.sh) using:
bash ./script.sh
Bind scripts that need user interaction via terminal window (fzfget.sh, fzfplay.sh) using:
xfce4-terminal -x ./script.sh
This will close them upon hitting ESC or Ctrl-X, or when hitting enter when picking a file via fzf.
