Issue: The new font size file created for one time only

[2023-FL]

Hi, I First of all, many thanks for your sharing this online app of converting truetype font to Adafruit GFX font; however, I found out that a new created font size file with an individual unique font size can not be save independently onto the local computer everytime. I have to change the new font file to use "save as" function to different location of folder in my local computer for keeping a new unique font size file.
Could you check the app again please?

Best regards,

Francis
