should be simple enough to do it yourself. replace everything starting from \TiTS-backer-0.9.016-win\resources\app to the linux folder. its extra work on my end and though I am working on the apk version
Edit: I feel like i didnt explain this enough. the folder with the index.html file (\TiTS-backer-0.9.016-win\resources\app) to the same folder that linux has the index.html file (never downloaded the linux version, but it should be the same hierarchy as the win version).
EDIT 2 (lmfao): make sure to delete all the js files in the folder before replacing them with the win version since some of them dont have the same name. instead of finding the ones that dont have the same name and deleting them, its better to just delete all .js files since you will be replacing them anyways (if enough people are having trouble I'll do a real guide)
