Just followed your guide antikythera
for installing TDF builds which went successfully and has some obvious benefits over Flatpak such as quicker file and config integration.
Should say for the present 220.127.116.11 is significantly more unresponsive in Writer and slightly more unresponsive in Calc spreadsheets than 18.104.22.168.
Have decided to go back to 22.214.171.124 and wait until a higher fresh TDF download is available and maybe try that.
My original plan was to find a guide like antikytheras but Flatpak came up in the search engine result first and piqued interest.
Also, another partial workaround to aforementioned bug is remove the standard.soc from ~/.config/libreoffice/4/user/config of LO 126.96.36.199 and replace with customized standard.soc.
